Application: knetworkmanager (v0.9)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-24-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
The crash happens as soon as you select the new interface (only testing with wired). I manually start knetworkmanager from the command line again, repeat the process and it crashes again. It happens about 4 or 5 times in succession and then it just works. 

The crash can be reproduced some of the time.

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