I looked a while and could not find this bug before reporting mine. I would not have at all if Michael Pardee did not point it out. So I will include my report and work around from 142780.
On Ubuntu 12.04 only. (Does not happen on 14.04) After upgrading the network-manager-gnome packages (includes libnm-gtk0 libnm-gtk-common) from 0.9.4.1-0ubuntu2.3 to 0.9.4.1-0ubuntu2.4 Disconnect, Edit and under VPN Connections Configure VPN and Disconnect VPN are greyed out and unelectable. You can no longer change passwords for VPN or WiFi, or define new static IP configurations. As 0.9.4.1-0ubuntu2.3 is no longer available in the repos, I had to roll back to 0.9.4.1-0ubuntu2, which meant rolling back Unity Greeter as well. This was initially found on my desktop, but replicated in a VM I had with 0.9.4.1-0ubuntu2.3 still running. Going directly to 0.9.4.1-0ubuntu2.4 still gives the same problem.
