Application: knetworkmanager (v0.9)
KDE Platform Version: 4.4.4 (KDE 4.4.4) "release 2"
Qt Version: 4.6.3
Operating System: Linux 2.6.34-12-desktop i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:
I was turning on Knetworkmanger after using ifup in yast for the last month. I was using ifup because of bug that disable the all networks in knetworkmanager. This bug was fixed about a week ago, so I decided to move back over.

This report repressents one of four crashes, I actual had to delete this file to get things to work.
rm /var/lib/NetworkManager/NetworkManager.state 

The crash can be reproduced some of the time.

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