                    applicatoin closes
           Product: dragonplayer
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: gregpayne at 1st-class-travel-taxis.com


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 2.6.31-21-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Insert a DVD disc, click the play disc button in draggon player, it seams to
read one file, i assume the first VOB then closes down and i get the crash
report as it tries to move onto the next file, again i am assuming the second
vob file
