Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.4 (KDE 4.3.4)
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:
This is probably a duplicate, but I can't identify which crash it's a part of.  I accidentally opened multiple mp4 files and when I tried to close them Plasma crashed with it.

 -- Backtrace:
