Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-13-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
What it says on the tin. It's just after the two boxes appear saying that it's been connected.

And sorry, I couldn't find debug packages for plasma-widget-network-manager. Do they even exist?
