Why does using Enigmail with Icedove on Debian fail if I don't start gpg-agent manually?

I'm using Icedove on a Debian Sid installation, and now I try to use Enigmail with it. But I encounter some issues:

I had to create my keys with gpg2 instead of Enigmail, because it didn't want to create a revocation key.

Now I can use my own created keys, but I have to restart gpg-agent before; otherwise Enigmail says "Error: encryption command failed".

$ ps aux | grep gpg
guik      4362  0.0  0.0 165796  1080 ?        Ss   17:02   0:00 gpg-agent --homedir /home/guik/.gnupg --use-standard-socket --daemon
$ pkill gpg-agent
$ gpg-agent --homedir /home/guik/.gnupg --use-standard-socket --daemon
gpg-agent[15507]: Attention : « --use-standard-socket » est une option obsolète — non prise en compte
gpg-agent[15508]: gpg-agent (GnuPG) 2.1.8 started

and then it works.

If I kill gpg-agent again and if I try to send an encrypted email, gpg-agent restarts by itself, and it don't even work.
I followed this guide and everything seems fine.

Enigmail uses this command to send:

enigmail> /usr/bin/gpg2 --charset utf-8 --display-charset utf-8 --batch --no-tty --status-fd 2 --comment "Using GnuPG with Icedove - http://www.enigmail.net/" -t --clearsign -u 0x41A33C73 --use-agent

I'm running Icedove 38.2.0 and Enigmail 1.8.2 (20150416-1748). It works neither on Gnome, nor on Cinnamon.

Anyone encountered similar issues ?

Thanks in advance !

Edit: I tried to downgrade on version 2.0.28-3 of gpg2/gpg-agent (available on testing/stable), and now, Enigmail refuse to recognize my old keys. But, when i upgraded agin to version 2.1.8, apt-listbugs warned me:

...
bogues de gravité grave sur gnupg2 (2.0.28-3 -> 2.1.8-1) <En attente de traitement>
b1 - #795639 - automated secret key import process for gpg2.1 skips some keys
bogues de gravité serious sur gnupg-agent (2.0.28-3 -> 2.1.8-1) <En attente de traitement>
b2 - #796931 - gnupg-agent: no longer writes $GNUPGHOME/gpg-agent-info-    $(hostname) file
Résumé :
gnupg-agent(1 bogue), gnupg2(1 bogue)

I'll try with other versions later

I do experience similar issues with Debian Jessie and only GnuPG 2.1 pulled from experimental, so it seems to be an issue with GnuPG 2.1. It did not bother me enough yet to further analyze the issue, but will gladly monitor your question. – Jens Erat – 2015-10-01T20:17:00.343

thanks for your response. i'm using gpg 2.1.8 with libcrypt 1.6.3. Maybe you're right, or maybe a conflict with gpg-agent and seahorse or gnome-keyring...? – guik – 2015-10-02T00:09:34.353

Why does using Enigmail with Icedove on Debian fail if I don't start gpg-agent manually?
