Reported using DrKonqi
Comment 1 RJVB 2016-12-07 12:27:39 UTC 
This was reproducible, and I think it was caused by the fact I had configured an icon theme which inherits the gnome icon theme. My KaOS install had only a partial version of that, just the 32x32 directory.

I don't think that should lead to a crash, though (nor an abort).
Comment 2 Martin Flöser 2016-12-07 19:44:46 UTC 
Unfortunately the backtrace is lacking debug infos and we don't see where it crashes. It looks like being an OpenGL driver crash.
Comment 3 RJVB 2016-12-07 21:02:24 UTC 
You're right, damn. DrKonqi gave 3 starts to the backtrace so I didn't look any further.

I'll have to figure out if KaOS has something equivalent to Debuntu's dbg packages. Not for everything, it seems.
Comment 4 RJVB 2016-12-08 10:11:03 UTC 
Annoyingly I haven't yet been able to reproduce the crash. I'll update this ticket if/when I can, but it certainly seems likely that the crash had something to do with compositing. In fact I'm surprised that I got acceptable desktop behaviour at all with compositing active; I have another system that I run both on real silicon and under VirtualBox and I keep having to toggle the feature (and that's VirtualBox under MSWin, which usually has better support for "advanced graphics").
