Application that crashed: kontact
Version of the application: 4.3.0 rc2
KDE Version: 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2))
Qt Version: 4.5.2
Operating System: Linux 2.6.30-1-amd64 x86_64
Distribution: Debian GNU/Linux 5.0.2 (lenny)

What I was doing when the application crashed:
When I did open a link into kontact - kmail after a little while kontact crashed.

Not sure if it's reproducible.

Cheers,
