Application: systemsettings5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-15-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
Selected decorations from the settings screen. I do have quite a few decorations installed and I noticed that scrolling was quite slow and jumpy the last time I changed decorations. Now when I enter decorations it just crashes.

The crash can be reproduced every time.

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