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:
I had installed several window decoration themes, including one named "OS X". I activated the OS X theme, which worked sucessfully. Now when I go back to switch themes, System Settings crashes every time I click "Window Decorations", just after generating the previews.

- Custom settings of the application:
"OS X" Window Decoration theme

The crash can be reproduced every time.

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