Application that crashed: kopete
Version of the application: 0.70.90
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2))
Qt Version: 4.5.1
Operating System: Linux 2.6.28-11-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
thats it, clicked on a icq contact (with no chatwindow for that contact yet) and kopete crashed. 

maybe the backtrace is somehow usefull.
