New crash information added by DrKonqi

plasma-desktop (0.4) on KDE Platform 4.7.2 (4.7.2) using Qt 4.7.4

- What I was doing when the application crashed:

- Unusual behavior I noticed:

The default panel was not working (nothing was clickable on it) so i tried to remove it and plasma desktop crashed. After plasma-desktop restarts i re-add the default pannel and it works. But when the computer is restarted same problem occures (unclickable panel).
