Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2))
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:
After attaching or dettaching a network interface (in my case, an smartphone) plasma crashes if the network manager applet is in use.  After removing it, the crash dissapears.
Using KDE 4.2.90. 

Reproducible everytime.
