Application: systemsettings5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-25-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- I installed some new themes using internal tool, one of them was "OS X", that apparently led to the crash. I was able to apply this theme, then application crashes everytime when I try to open page with theme preview window.

The crash can be reproduced every time.

-- Backtrace:
Application: Параметры системы (systemsettings5), signal: Segmentation fault
