Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1))
Qt Version: 4.5.1
Operating System: Linux 2.6.30-6-generic x86_64
Distribution: Ubuntu karmic (development branch)

What I was doing when the application crashed:
Default KDE Network Management Control Module shows no existing network connections, even though there are and they are active. Manually creating one crashes the Control Module. Reproduceable every time. This is on Kubuntu Karmic daily x64 with latest repo builds. Installing debug libs now and will update bug with backtraces once they are installed. 

Note, this is originally a Ubuntu Karmic x64 install with KDE installed along-side GDM using apt-get install kubuntu-desktop. Shouldn't matter though, running multiple desktop managers isn't out of the ordinary.
