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 2.6.30-1-686 i686
Distribution: Debian GNU/Linux unstable (sid)

What I was doing when the application crashed:
I wrote some reply to a bug report on bugs.kde.org and switched applications. An hour or two later, I realized that there had been a timeout while trying to submit the update. I clicked the "back" button and konqui crashed.
