Application: knetworkmanager (v0.9)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-34-generic x86_64
Distribution: Ubuntu 10.04.3 LTS

-- Information about the crash:
This appears to be an intermittent issue.  KNetworkManager had been working OK for quite a while but it looks like I encounterd an old issue I don't recall encountering on this host before now.  I'll check for recent changes to system state and share any additional clues I find.

The crash can be reproduced some of the time.

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