networkmanager-openvpn will not connect

[John Frankish <j-frankish slb com>]

Using networkmanager-openvpn- 0.9.8.4 patched to use libsecret, I am unable to connect.

After configuring the vpn connection using gnome-control-center, I'm prompted for the vpn password, but after 
entering it I get the error " Connection activation failed: the VPN service failed to start".

Running from the command line gives the output below.

The tun module is compiled into the 3.8.13 kernel I'm using (CONFIG_TUN=y), is this the source of the error?

Regards
John
