           Summary: Closing a window running an mp4-file crashes dragon
           Product: dragonplayer
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: arne_bab at web.de


Application: dragon (2.0)
KDE Platform Version: 4.5.86 (4.6 >= 20101210) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.34-gentoo-r6 x86_64
Distribution: "Gentoo Base System release 2.0.1-r1"

-- Information about the crash:
- What I was doing when the application crashed:

I closed the window on an .mp4 movie. It doesn’t matter, if I wait till a movie
is finished or just close it after start. It doesn’t happen when no movie is
loaded. It also doesn’t happen for .avi files. I didn’t check other file
formats, yet. 

Best wishes, 
Arne
