Installing Didier's new wallpaper, I get it on all of gdm, current user and new user.
So the issue happens when you install a new Maverick machine after the new ubuntu-wallpaper has been uploaded in Natty.
In this case, the cache is newer than the new wallpaper and so won't be rebuilt, leaving the user with the old wallpaper.
