           Summary: Plasma crashed when closed an empty panel
           Product: plasma
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: plasma-bugs@kde.org
        ReportedBy: cubranic@acm.org


Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
While customizing my newly installed KDE 4.3 desktop, I added a new panel. It
was created floating over the desktop (instead of attached to an edge), and I
never added anything to it. Some time later, I closed it, and Plasma crashed
with the attached stack dump.
