           Summary: Plasma crashed on logout (shutdown)
           Product: plasma
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: panel-devel kde org
        ReportedBy: Regnaron web de


Version:            (using Devel)
Installed from:    Compiled sources
OS:                Linux

Setup:
I ran kontact (kmail) in a recent KDE4 SVN snapshot via a liveCD (http://grundleborg.wordpress.com/2008/05/25/kde-pim-krush-day-is-now/) in a virtual machine. When kontact froze, I killed the process. After that I shut down the KDE4 session. Instead of shutting down, plasma crashed with the backtrace below. (Only konsole was still open at that time)

Application: Plasma Workspace (plasma), signal SIGSEGV
