           Summary: Activate window using task bar
           Product: kde
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: morpheuz at gmail.com


Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1))
Qt Version: 4.5.1
Operating System: Linux 2.6.29-custom i686

What I was doing when the application crashed:
Selecting an item on the taskbar sometimes crashes the whole plasma. Sorry,
didn't have more time to track this bug down. Creating this bug entry more as a
reminder ;)
