Bug 238121

Application: knetworkmanager (v0.9)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
When I would select a VPN network that uses vpnc Cisco client, knetworkmanager would segfault and never do anything with the connection.
