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

1. Open up: System settings --> Application Style --> Window Decorations --> tab Buttons
2. Drag the pin on the top of the sample window from left to right and back a few times.
3. The application crashes.

The crash can be reproduced every time.
