Thanks.

So does it generally work after it restarts?

Can you find any pattern?

Yes, it works after restart. I now also experienced crashes with similar stacktrace on another pc with same distribution+version, but with radeon graphics. Here the crash appeared:
- clicking to configure the new volume-applet
- in the configuration dialog of that applet: trying to change  to the "shortcuts" section
