Bug 212441

Application that crashed: knetworkmanager
Version of the application: v0.9
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
knetworkmanager crashes when NetworkManager is killed. This seems to occur everytime this occurs (which is frequently because NetworkManager periodically refuses to connect to wifi and restarting it solves the problem)

 -- Backtrace:
Application: KNetworkManager (knetworkmanager), signal: Segmentation fault
The current source language is "auto; currently c".
