Arch Linux

Additional info:

* gajim 1.0.3-1
* kde 18.04

Steps to reproduce:

Installed gajim and started for the first time, i got a traceback (see below).
Installing 'python-dbus' fixed it for me, should it be added to the dependencies list?

I also installed 'python-pillow' to view all avatars in the gajim roster.
Maybe also a candidate for an (optional) dependency?
