Application: systemsettings5 (5.8.2)

Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.8.2-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

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

0. Start System Settings
1. Click "Color"
2. Select another Color Scheme, marking this screen dirty (so the application would ask you to decide wether to save the new settings or to discard them
3. Return to all Settings
BAAAAAAAAAM
4. The application is dead :(

The crash can be reproduced every time.

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