Same issue here. However I may have stumbled onto the solution. I was getting the same diagnostic messages as Paul McCann, to wit:
[Paul] when I run nm-connection-editor I can see the terminal throw error
[Paul] ** (nm-connection-editor:7787): WARNING **: Invalid setting VPN: ca
[Paul] This leaves the save button grayed out and I am unable to join my VPN network
It turns out this was due to me not having entered CA info, even though I chose password authentication. I don't know if this is a functional bug (demanding CA info even when using password authentication), or just a lack of indication of what's missing (e.g. a message saying "You still need to enter CA info in all cases").

This was on Linux Mint Maya.
