Bug 346180

Application: systemsettings5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-10-generic x86_64
Distribution: Ubuntu Vivid Vervet (development branch)

-- Information about the crash:
- What I was doing when the application crashed:

I had selected a specific theme in the Window Decoration thing. Can you please stop this window from interfering with my typing? I don't want it to show how good I am doing, okay?

Fine, it's gone now. Bug reporting is an anomoly in this system. It drives me crazy.

I had selected a regular theme for the Window Decoration in the application settings thing.

- Custom settings of the application:

The theme I had installed was a  transparent Oxygen theme.

The crash can be reproduced every time.

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