Dear Maintainer,

the latest update 2.6.0-1 has rendered gajim unusable on Debian
Testing, as the package python3-nbxmpp is currently only available in
version 7.3.0-1 (which matches the package dependencies). Attempting to
launch gajim from a terminal results in the following output:

Attempting to launch gajim from a graphical UI results in the program
not appearing and not showing any information at all.

A correctly set python3-nbxmpp version in the dependencies would have
prevented apt from updating gajim until the required dependency is
available, keeping the software usable.
