Bug 221921

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-17-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I have had this problem many time.
First after a update plasma crash, then after installing facebook plasma, third after ... nothing and now just before I have installed a super Karamba theme, first time...
Each time this is after a reboot but this is the first time the bug manager launch himself.
I can use Alt+F2, Alt+TAB and each windows opened before the crash resume normally. But that all everuthing else is... void.
