Was just about to upload the gnome-screensaver fix and then I realised it doesn't work in this case: When you switch users (e.g. to guest) indicator-session locks the screen then does the switch. With this change this causes lightdm to both start a greeter and a new session. I think the correct fix is for indicator-session to not attempt the lock when running under lightdm and get the lightdm daemon to always lock sessions when switching away from them.
