           Summary: Crashes while playing a DVD with no obvious cause
           Product: dragonplayer
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: rvalkass at gmail.com


Application: dragon (2.0)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-23-generic x86_64
Distribution: Ubuntu 10.10

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

Watching a DVD. It had been playing fine for approximately 40 minutes, then
decided to close for no reason. I performed no interaction with the window at
the time of the crash. I didn't even have the mouse or keyboard in my hands!

The crash can be reproduced some of the time.

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