Qt Version: 5.5.0
Operating System: Linux 4.1.6-200.fc22.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:

in the settings, changing compositor settings and hitting overview to go back to the main menu, other options don't crash the app.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
