Application: knetworkmanager (v0.9)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-25-generic i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
While attempting to connect to a mobile broadband network (using Huawei E220 USB modem), knetworkmanager crashes and I lose any network connection.  I have to restart the application and manually reconnect to networks to regain connection.  Often knetworkmanager will crash successively each time I attempt to connect to this network, but occasionally it successfully connects.

The crash can be reproduced some of the time.

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