           Summary: crash when launching kmail
           Product: plasma
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: widget-lancelot
        AssignedTo: ivan.cukic+kde@gmail.com
        ReportedBy: greg.martyn@gmail.com


Application that crashed: lancelot
Version of the application: 1.7
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.30.5-43.fc11.x86_64 x86_64

What I was doing when the application crashed:
I clicked the lancelot button, searched for kmail, used the arrow key to get to
"run kmail" then pressed enter.

In thread 1, I see that the top of the call stack is different from my
backtrace, but the rest looks the same.

 -- Backtrace:
Application: Lancelot (lancelot), signal: Segmentation fault
