Application that crashed: konqueror
Version of the application: 4.3.4 (KDE 4.3.4)
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-3-686 i686
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
Konqueror 4.3.4 on Debian Squeeze with kpart-webkit installed always crashes when trying to open video's URL http://www.glatzor.de/fileadmin/files/screencasts/packagekit/gai-using-pk.ogg

Same behaviour with Arora - which probably means it's actually webkit bug?
