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

- Unusual behavior I noticed:
The button Logoff  not activate when you press to shutdown the computer nothing hapend 
No icon for the sound on the bar at the bottom of the screen..


Very strange another account is running ok. I destroyed my account and recreate it using same user identification and have the same problem

The crash can be reproduced every time.
