Application: kopete (0.99.80)
KDE Version: 4.3.69 (KDE 4.3.69 (KDE 4.4 >= 20090923)) (Compiled from sources)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-1-686 i686
Distribution: Debian GNU/Linux 5.0.3 (lenny)

What I was doing when the application crashed:
When using kopete from gnome through ssh to localhost and receiving a message it launches a notification that appears from above and it crashes with segmentation fault everytime. I'm using kopete from sources and also qt from kde git branch.

 -- Backtrace:
Application: Kopete (kopete), signal: Segmentation fault
