Application that crashed: dolphin
Version of the application: 1.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.30-2-686 i686
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
Drag and drop a file to Iceweasel Window.
Dolphin just crashes when entering the Iceweasel window. A Dolphin Filter was set to reduce shown files.
