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:
- installed some of the most favorite and most often downloaded styles (maybe 5 or 6 ones)
- scrolled in preview window to choose one of the previously installed styles
- instant crash while rendering previews...
- now I am unable to change ANY style setting, because this systemsessings-modul crashes instantly on startup... -> fatal bug!!!

The crash can be reproduced every time.

-- Backtrace:
Application: Systemeinstellungen (systemsettings5), signal: Segmentation fault
