Application: dragon (2.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-21-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Every time I try to play a .avi video file, Dragon player only shows a screen with weird orange streaks and then crashes. This happens every time. All codecs are installed, and the same video files play fine on VLC.

The crash can be reproduced every time.

 -- Backtrace:
Application: Dragon Player (dragon), signal: Aborted
