backtrace knetworkmanager crash

Description David Benjamin 2009-11-24 01:10:35 UTC
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 2.6.31-14-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
When restarting NetworkManager (Ubuntu Karmic, via service restart network-manager), knetworkmanager consistently crashes. The backtrace appears to be different from the other ones, so here's another report.

(This Crash Reporting Assistant is rather fancy; I'm impressed. Although, it's not so good about noticing reports that are duplicates of candidates for duplicates.)

 -- Backtrace:
Application: KNetworkManager (knetworkmanager), signal: Segmentation fault
The current source language is "auto; currently c".

The backtrace is indeed a bit different, but it is probably related to bug 210878.
@Will: what do you think ?

Offtopic: the duplicate handling was already improved in KDE4.4 (4.3.4 should get a minor fix to display more accurate possible duplicates too...)

New crash information added by DrKonqi

knetworkmanager (v0.9) on KDE Platform 4.4.95 (KDE 4.4.95 (KDE 4.5 >= 20100723)) using Qt 4.6.3

- What I was doing when the application crashed:

I restarted NetworkManager with the command /etc/init.d/network try-restart and then KNetworkManager crashed.

I believe I may have hit the same or a similar bug. But before the crash of KNetworkmanager,
I had an update of the NetworkManger rpm and therefore restarted the network (rcnetwork restart).

Hope the backtrace helps.
