Gajim is missing the rundep python-importlib-metadata
Also gajim 1.2.2 is available which will require adding python-css-parseras a rundep and updating python-nbxmpp to 1.0.2.
I've done this myself locally an it seems to work fine. But I would prefer someone who actually uses gajim to test it, as I've never used it before today. I couldn't find anyone to help so decided to make this task instead.
