You don't need joints, you create your camera, and it will have translates,rotates, scales, etc in channel box like a peice of geometry has. You can key the position, angle and all other camera related stuff either there or in the attribute editor.
You can also attach them to motion paths made from curves.
It's now on all scenes I noticed. Even my animation test scene. It doesn't display any errors since it doesn't do anything. You would expect it would at least show the option box, but nothing. Maybe a re-install will fix it.
