           Summary: networkmanager plasma crash when interface is removed
           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: dazjorz at dazjorz.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 2.6.30-6-generic x86_64
Distribution: Ubuntu karmic (development branch)

What I was doing when the application crashed:
This crash happened for me while installing and uninstalling (unloading)
VMware; it unloads a kernel module causing two network interfaces to be
removed, causing this crash.
However, I could not find the debugging packages for
plasma-widget-network-manager on Ubuntu, so I can't provide a better backtrace
at this moment. I think I can reproduce.
