Application that crashed: konqueror
Version of the application: 4.3.00 (KDE 4.3.0)
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-1-amd64 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
I was downloading a file, but for some reason it stalled (I've noticed this happens sometimes). So I stopped the job by pressing the stop button in the notification window. A small window popped up telling me the server is not responding (yes, I already guessed that much). I click okay, and then Konqueror crashed.

Apprently the backtrace is 3-stars useful. So here it is. :-)
