Comment 1 Linus Lewandowski 2017-01-23 23:20:49 UTC 
Had similar crash on ArchLinux every time when I:
1. Open the "Application Style" group
2. Randomly switch ~5 times between kcms ("Widget Style", "Window Decorations", "GNOME Application Style (GTK)")
3. Go back to the main screen
4. Repeat up to 3 times.
