           Summary: Dragon Player crashed when closing multiple files, one
                    by one.
           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: mark_hayes_1973 at hotmail.com


Application: dragon (2.0)
KDE Platform Version: 4.5.5 (KDE 4.5.5)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

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

I was closing the Dragon Player files by clicking on the X on the top right
hand side of the window to close each file.  I had closed two (of the three
open files) without problems - but when I clicked on the last one to close down
Dragon Player completely, the program crashed and a bug reporting window opened
up.

-- Backtrace:
