Bug Description

I have a vpn-connection here which was working fine till recently. The configuration was imported from an openvpn config file and when run directly via "openvpn <config>" everything's fine but networkmanager fails on it. When I try to connect the first time network manager reports "success" but fails indeed and no connection is brought up. But reports "failure" for any further tries.

I think the essential lines from syslog are:
