Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.3 (KDE 4.3.3) "release 3"
Qt Version: 4.5.3
Operating System: Linux 2.6.27.39-0.2-default i686

What I was doing when the application crashed:
Plasma Could not initiate the desktop screen.
This only happen when i have not connected wire LAN .
But, if the wire LAN connected to internet, firstly, then the plasma will running properly.
I guess the  problem with my knetwork manager (maybe using KDE3).
