Bug 237771

Application: knetworkmanager (v0.9)
KDE Platform Version: 4.4.3 (KDE 4.4.3)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
For some reason, the taskbar widget for the network manager reported that it was disabled. Restarting the network-manager service (I'm running kubuntu) didn't appear to resolve the problem, and nothing was possible from the System Settings application.

Upon running KNetworkManager from the command line, the program crashed. Now, everything appears fine.

The crash does not seem to be reproducible.

 -- Backtrace:
Application: KNetworkManager (knetworkmanager), signal: Segmentation fault
