Application: knetworkmanager (v0.9)
KDE Platform Version: 4.4.2 (KDE 4.4.2) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.33-gentoo-r1 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
After plugging in an ethernet cable, knetworkmanager automatically starts the "Auto (eth0)" profile.

There is no DHCP this LAN segment, so I have configured a static profile, which I then select (while the Auto profile is trying to get an address).

This randomly causes a segfault.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: KNetworkManager (knetworkmanager), signal: Segmentation fault
Traceback (most recent call last):
