Could you please try to reproduce with Wicd Client KDE 0.3.0? There is no Ubuntu package, but you can try with the Debian package: http://packages.debian.org/sid/wicd-kde
Comment 2 a.pronobis 2012-03-19 08:40:55 UTC 
Seems to work. I get a different crash now caused by kwin now :)

New crash information added by DrKonqi

wicd-kde (0.2.3) on KDE Platform 4.8.5 (4.8.5) using Qt 4.8.1

- What I was doing when the application crashed: Everytime I attempt to either log out or shutdown I get a WICD crash notification. If I just click on close the shutdown process continues.
