Comment 9 for bug 284212

Playing manually with the auth dialog:

1. Run

   /usr/lib/network-manager-pptp/nm-pptp-auth-dialog -u 1234 -n lalala -s org.freedesktop.NetworkManager.pptp

2. Enter some password
3. Check 'remember password for this session'
4. Press 'Ok'
5. ^C the program because it doesn't close for some reason
6. Run it again
7. Watch it crash and burn:
