Application that crashed: knetworkmanager
Version of the application: v0.9
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-15-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
when manually starting network-manager from the command line, knetworkmanager tries to start up and crashes. Restarting knetworkmanager manually works fine.

(To be honest, I'm pretty convinced this is a dup of the bug I marked this a possible dup of, which again is a dup of some other bug. Unfortunately I wasn't able to tell which bug would be used to track this, or why I'm even still filling out a detailed bug report.)
