When I moved entire ~/.config to ~/.config.bak I was able to log in, just like with a new user. So the culprit seems to be located somewhere in ~/.config.
EDIT: the thing causing problems for me was ~/.config/dconf/user. I’m gonna purge that and recreate my Gnome settings.
EDIT 2: well, gnome is still throwing core dumps and restarting on some occasions, but at least I can use the system.
@ehb00, my comments get deleted on the arch linux bugtracker so I’m gonna ask my question here. It seems I’m not a “sacred arch user”, and I’m not allowed to comment there. This zealotry is very counter-productive but so be it.
which commit did you use that fixed the issue for you? I’ve downgraded to commit d5abf1b1ba3209b167efac5bf531193dd3d91b85 (tag: 1.8.3-6) and I just had another crash, with about the same logs.
