Application: systemsettings5 (5.3.2)

Qt Version: 5.4.2
Operating System: Linux 3.16.7-24-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I want to change the selected theme for my plasma 5. Whenever I select "window decorations" option the system settings is crashing with a segmentation fault 11 error.  I reported a kwin issue with similar error. And it may be related to proprietary drivers, but it is hindering normal usage of plasma 5.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
