Description of problem:
Connecting to a Cisco VPN with vpnc via NetworkManager fails

Version-Release number of selected component (if applicable):
NetworkManager-vpnc-0.7.0-0.10.svn4175.fc10.x86_64


How reproducible:
Always

Steps to Reproduce:
1. Configure vpnc connection
2. Try to connect
3.
  
Actual results:
Connection fails immediately with "The VPN connection 'XXX' failed", and no other details.

Expected results:
Should connect

Additional info:
I'm using an RSA token, so the password is never saved.  The group password is saved.

Strace shows (XXX=redacted):
4573  read(0, "Script /usr/libexec/nm-vpnc-service-vpnc-helper\nCisco UDP Encaps

4573  read(0, ""..., 4096)              = 0

4573  write(2, "missing IPSec secret"..., 20) = 20
4573  write(2, "\n"..., 1)              = 1

This was working fine with the previous version (1:0.7.0-10.svn4024).  This is a regression in the Oct 12 update (1:0.7.0-10.svn4175).
