           Version: unspecified

            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: panel-devel kde org
        ReportedBy: bugsbane gmail com


Version:            (using KDE KDE 4.0.0)

I haven't managed to replicate this consistently but wanted to pass along the backtrace in case its useful. It happened just as I grabbed the Kget droptarget and moved it over the Desktop pager in the taskbar.
