Same issue and starting nm-connection-editor does not solve the problem.
Adding an OpenVPN connection with; Connection Name Gateway Type=Password Username Password CA=None
when I run nm-connection-editor I can see the terminal throw error
** (nm-connection-editor:7787): WARNING **: Invalid setting VPN: ca
This leaves the save button grayed out and I am unable to join my VPN network
Ubuntu 12.04.2 LTS
