-- Information about the crash:
- What I was doing when the application crashed: Just log-in and got black screen with aplication window. The application themselfs works OK. But this problem happen only with this user account and there is no problem with other accounts. There was no special activity before it happend first time. Normal work, normal shut-down and next time black screen with crash reporting window.

The crash can be reproduced every time.
