There are some known bugs with the upload stash, please upgrade to MediaWiki 1.24 (just released) which includes some fixes, hopefully solving the error for you too.
The next thing you can do, given your files are so small, is to visit Special:Preferences on your wiki and disable "chunked uploading". You'll then use the standard upload, which is less powerful but usually less fragile.
If that fails as well, probably the issue is deeper, e.g. you might have misconfigured the upload directory. Better double check your uploads configuration and enable debugging (see Manual:Debug) to have more details on your error. If that doesn't help, please file a bug at http://phabricator.wikimedia.org.
