Comment 8 for bug 378718

First at all, Feranick, thanks for the backport :) Anyway, it keeps no working :-/

Although the "Add button" is clickable right now thanks to network-manager-openvpn plugin backported from intrepid, the problem seems to be related to an older version of openvpn which doesn't work with network manager, as it's said here:
https://bugs.launchpad.net/ubuntu/+source/network-manager-openvpn/+bug/260291

JFYI, my current versions are:

$ dpkg -l openvpn
   Version 2.1~rc7-1ubuntu3.3

$ dpkg -l network-manager
   Version 0.7~~svn20081018t105859+m
