           Summary: Plasma  Crash in  Plasma::Extender::items
           Product: kde
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: paragw at excite.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 2.6.30-rc6 x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
This happened when the machine was left idle copying files over to another
drive. File copy finished notification was there after crash and restart so it
may not have anything to do with the crash. 

 -- Backtrace:
Application: Plasma Workspace (plasma-desktop), signal: Segmentation fault
