Bug 347913

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:
I opened the system settings. There I have choosen "workspace design" or whatever it is called in english. It crashes instantly.
Note: The system is a fresh installation. So far I have only choosen the recommended binary nvidia drivers and am currently in the middle of a system update.
After the update is finished I will do my first restart and check again.

The crash can be reproduced every time.

-- Backtrace:
