Works for me in Ubuntu GNOME 13.04. I have changed to lightdm using the following:
apt-get install --no-install-recommends lightdm unity-greeter
After that, "Lock" and "Switch user" works correctly. I have the "alternative status menu" plugin installed (see http://askubuntu.com/a/115207/30266), don't know if this affects matters.
