Application that crashed: dragon
Version of the application: 2.0
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Opened a QuickTime video file created by ScreenToaster (screentoaster.com) on Mac OSX. Dragon Player and Kaffeine both immediately crash on opening (both using Xine?) Installed the libxine-dbg package and regenerated crash report, which then went to 'useful' (three stars).

Will try to upload the video file if I can.
