nm-vpn-mananger crash if no group password entered

[Ken Teague <kteague pobox com>]

NetworkManager v6.5
NetworkManager vpnc plugin (from Debian backports)
Debian Lenny (testing)
vpnc v0.5.1r275

 
I imported my .pcf file, went to login, but didn't (at the time) have my group password.  I simply entered the regular password, left the group password blank, and proceeded with authentication when this happened:

This caused nm-applet to crash/disappear but I was able to restart it a la /etc/init.d/network-manager restart.  FWIW, the NetworkManager daemon was still running.
