Bug 246812

Application: knetworkmanager (v0.9)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.33.6-147.2.4.fc13.x86_64 x86_64
Distribution: "Fedora release 13 (Goddard)"

-- Information about the crash:
It is very common on my machine for Knetworkmgr to die when I'm turning VPN on/off.  Unfortunately the VPN connection isn't very stable (don't know whose fault that is yet) so I'm forced to re-activate it often.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: KNetworkManager (knetworkmanager), signal: Segmentation fault
82	T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS)
