kdeinit5 fails constantly with Fedora 29

Question

I'm using Fedora 29 + KDE 5.14.5 + KDE Framework 5.59.0 + QT 5.11.3. For last couple days I'm getting lot of kdeinit5 crashes. I have no idea what is causing that crashes, there is no specific action that leads to fail. In logs I get such info:

I have checked all other SO topic with the same issue and there is no definite answer. Can anybody point me to a problem that is causing all that crashes?

Answer 1

I was encountering the exact same issue on a fresh Fedora 29 installation and was baffled. As @snegovik noted, crash reliably occurs when closing dolphin, and that was driving me insane. The solution as per snegovik's answer is to downgrade, but the repos already removed the older kf5-* packages.

However, there is still hope. Fedora apparently has some older packages on the Koji build system, and kf5-*-5.58.0-1 packages are available.

https://koji.fedoraproject.org/koji/buildinfo?buildID=1268224

There's quite a few packages so I extracted the URLs from the web source. Here's the command I ran:

sudo dnf install \

Last step is to keep the packages back to prevent accidentally upgrading back to 5.59.0-1. I added this to /etc/dnf/dnf.conf:

excludepkgs=kf5-kio kf5-*-*

Note I used kf5-*-* and not kf5-* because there's some other packages like kf5-kdbusaddons.x86_64 that seem fine if they're upgraded.

Answer 2

Sorry - can not comment yet - had to use answer section. Hit the same problem on Fedora 29 with KDE5. Getting this error mostly right after I close dolphin:

We are sorry, kdeinit5 closed unexpectedly.
You cannot report this error, because kdeinit5 does not provide a bug report address.

This is a result of kf5-* updates. Checked another system with kf5-* version 5.58.0-1 and did

dnf update -x kf5-*

Result - NO ERRORS. Updating kf5-* version 5.58.0-1 to kf5-* version 5.59.0-1:

dnf update

Result - ERRORS.

Did some more digging:

1. Removed NVIDIA drivers from the system - running on nouveau only. Errors still persist.
2. Used another system with AMD RX580 video - same result: Errors still persist.
3. Did: dnf reinstall kf5-*- same result: Errors still persist.

Conclusion - this error does NOT relate to any particular video driver. This error relates to latest kf5-* version 5.59.0-1 update ONLY. Unfortunately you can not downgrade to kf5-* version 5.58.0-1 - as it is already removed from servers.

EDIT1 September 03 2019:

I did a bit more digging over the weekend. All latest versions of kf5-kio starting from 5.59.0 have that bug. Checked also 5.60.0 and 5.61.0

Thank you rayting for providing a link to the old (kf5-5.58.0) source - it saved me!

Here is what I did: I think it will break all warranties from Fedora (if you have any) but this works for me. Please do not blame me if it breaks your system :-)

1. List all application groups installed on your system - including hidden ones (as root or use sudo if you have it configured):

   dnf group list --hidden
   sudo dnf group list --hidden

2. Install all required development packages (may take a while) and make sure everything is up to date: Warning: May add to your system significant amount of used space - make sure you have enough storage.

   dnf -y group install "C Development Tools and Libraries" "KDE Software Development" "KDE Frameworks 5 Software Development" "RPM Development Tools"
   sudo dnf -y group install "C Development Tools and Libraries" "KDE Software Development" "KDE Frameworks 5 Software Development" "RPM Development Tools"

   dnf update
   sudo dnf update

3. Open konsole as user and download source for kf5-kio-5.58.0-1:

   wget https://kojipkgs.fedoraproject.org//packages/kf5-kio/5.58.0/1.fc29/src/kf5-kio-5.58.0-1.fc29.src.rpm

4. Install source rpm:

   rpm -Uvh kf5-kio-5.58.0-1.fc29.src.rpm

5. Change to a SOURCES directory that was created:

   cd ~/rpmbuild/SOURCES

6. Extract archive for kf5-kio:

   tar -xf kio-5.58.0.tar.xz

7. Move extracted directory to kio-5.59.0 (this is cheating! :-)

   mv kio-5.58.0 kio-5.59.0

8. Compress this directory:

   tar -cJf kio-5.59.0.tar.xz kio-5.59.0

9. Modify .spec file to display a "NEW" version and release:

   sed -i -e "s/Version: 5.58.0/Version: 5.59.0/g" ~/rpmbuild/SPECS/kf5-kio.spec
   sed -i -e "s/Release: 1%{?dist}/Release: 33%{?dist}/g" ~/rpmbuild/SPECS/kf5-kio.spec

10. Build a new srcrpm:

   rpmbuild --bs ~/rpmbuild/SPECS/kf5-kio.spec

11. Rebuild src rpm (will take 5-10 minutes depending on your hardware):

   rpmbuild --rebuild ~/rpmbuild/SRPMS/kf5-kio-5.59.0-33.fc29.src.rpm

12. It will also build "debugsource" and "debuginfo" packages (can someone direct me on how to permanently disable that on Fedora?): Remove these and update your kf5:

    rm -f ~/rpmbuild/RPMS/*/*debug*
    ls -las ~/rpmbuild/RPMS/*/*
    su
    dnf update %(user_home)/rpmbuild/RPMS/*/* 

13. After that close and reopen Dolphin - then try to close it again - you should have no more crashes.

Conclusion: There was a change in kf5-kio package between version 5.58.0 and 5.59.0 that is still persists in versions 5.60.0 and 5.61.0 that is causing kdeinit5 to crash on Dolphin close. Only after fixing this bug (on KDE part) and back-porting that fix to kf5 versions 5.59.0, 5.60.0 and 5.61.0 the crash will not be produced anymore.

Answer 3

This bug appears to be fixed by the this commit to KDE:

Summary: All QTextCodec are deleted by QCoreGlobalData on exit, so they must be allocated on the heap. Before Qt 5.12, it is even not allowed to delete them.

BUG: 408797

An update to Fedora 29 has been submitted, FEDORA-2019-01dfc11f76

By following that link above, then builds, one can get to the koji build of the kf5-kio-5.90.0-2 package for that pending update: https://koji.fedoraproject.org/koji/buildinfo?buildID=1392448

From there it is possible to download the RPMs and install them. I've found that only kf5-kio-core-5.59.0-2.fc29.x86_64.rpm need be installed to fix this issue, as it contains the file.so library with the bug. It can be installed individually, without the other RPMs from the build, via sudo rpm -Uvh kf5-kio-core-5.59.0-2.fc29.x86_64.rpm --nodeps.

Force installing and ignoring dependencies like this is not generally a good idea, but the -2 build here only fixes this bug from the -1 build so it's probably safe, and I've seen no problems so far. And Fedora 29 should get the update released sooner or later, at which point dnf will update everything.

Answer 4

The other two answers explain with precision what the problem is and how to build an older version while we wait for a fix. I also found a detailed thread here for which one of the users suggests setting the KDE_DEBUG=1 environment variable.

I went that route since it was fast but forgot to post back, so for solidarity if you add something like this to your shell startup login file (e.g., ~/.bash_profile not ~/.bashrc):

export KDE_DEBUG=1

then this will prevent you from getting this, but also ANY OTHER crash reports. The only noticeable impact this had on my setup was that KDE_DEBUG doesn't seem to play well with high DPI screens, so I used System Settings to scale the monitor up.

Doing this comes with other consequences I'm sure, but since I was editing my ~/.bash_profile and realized I never directed this "trick" here, thought I would post back...
