Qt Version: 5.5.0
Operating System: Linux 4.1.12-1-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Trying to change some window decoration preferences. Before an update this option was working well.
- Unusual behavior I noticed:
Crash on entering in window decoration preferences-
- Custom settings of the application:
Breeze theme, OpenGL 3.1

The crash can be reproduced every time.

-- Backtrace:
Application: Preferencias del sistema (systemsettings5), signal: Segmentation fault
