Application: plasma-desktop (0.3)
KDE Version: 4.3.66 (KDE 4.3.66 (KDE 4.4 >= 20090828)) (Compiled from sources)
Qt Version: 4.6.0
Operating System: Linux 2.6.31-9-generic x86_64
Distribution: Ubuntu karmic (development branch)

What I was doing when the application crashed:
NOTE: This is with Qt 4.6 in git <-------- 

kdeinit4 crashed taking plasma-desktop out when closing a plasmoid. I just started KDE trunk up, closed OpenBrain then plasma kdeinit4 crashed. I dont know if I can reproduce this or not.
