Application: knetworkmanager (v0.9)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-28-generic i686
Distribution: Ubuntu 10.04.2 LTS

-- Information about the crash:
knetworkmanager consistently crashes when attempting to change wireless network connections while connected to an existing wireless connection. This only occurs when knetwork manager is started automatically when the desktop environment is loaded. If knetworkmanager is restarted automatically after a crash the same crash occurs, however if knetworkmanager is manually started from the k menu or other manual method the crash does not occur. 

The crash can be reproduced some of the time.

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