Application: knetworkmanager (v0.9)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-20-generic x86_64
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
Happens every time when connecting to my work VPN (MS 2003 server).

After searching the bug base I tried launching it from konsole with a different style, e.g "knetworkmanager --style plastique" (or bespin), this *works* every time, no crashes.

If I launch knetworkmanager with no style (my system style is Oxygen) or with "knetworkmanager --style oxygen" it crashes every time.

If I change the system style to plastique and start knetworkmanager it works. If I then launch it with "style oxygen" it then crashes.


If I start with system style knetworkmanager connects fine. If I disconnect and change the style to Oxygen, then try to connect again it crashes.

Note:After repeated testing I sometimes get a zombie knetworkmanager that can't be killed with "killall", it takes a "kill -9" to get rid of it. Until the zombie process is killed knetworkmanager always crashes no matter what the style.
