Bug 275264

Application: dragon (2.0)
KDE Platform Version: 4.6.80 (4.7 Beta1) (Compiled from sources)
Qt Version: 4.7.3
Operating System: Linux 3.0.0-rc1 x86_64
Distribution: "Gentoo Base System release 2.0.2"

-- Information about the crash:
- What I was doing when the application crashed: Opening an arbitrary video

This happens with dragon player 2.0 on KDE 4.6.80 with phonon-vlc 0.4 and vlc 1.2.0-git. Standalone vlc works.

The crash can be reproduced every time.

-- Backtrace:
Application: Dragon Player (dragon), signal: Segmentation fault
