Comment 116 for bug 1297849

Wouldn't this also apply to Vivid? I look at find that the upstream code should be about the same:
https://git.gnome.org/browse/network-manager-applet/tree/src/shell-watcher.c?h=nma-0-9-10#n154

To ship a fix like this as SRU, it would first need to land in the current development release assuming it's still a problem there. I can't reproduce the issue here; using Unity. I can successfully reconnect to my VPN regardless of whether the previous connection was disconnected normally or failed.
