Application: knetworkmanager (v0.9)
KDE Platform Version: 4.4.1 (KDE 4.4.1)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-17-generic i686
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
What I was doing:
I selected one of the wired network settings (in addition to the "auto" one, I also added one where I set the DNS server manually), then NetworkManager crashes. This happened several times, though not each time I change the options (every 3rd time, I'd estimate).

The crash can be reproduced some of the time.

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