[arch-general] Gajim doesn't start

[SET]

Gajim fails to start with this backtrace, since upgrade 2 days ago, and there's no newer 
version available.

     *  Traceback (most recent call last):

Should it be reported to the package maintainer, or to bugs.archlinux, or to Gajim's 
developpers ? Or do I miss a package ?

Regards.
