Public bug reported: I don't know for a fact that Ubuntu isn't running mutter using GTK2, but I suspect that it's probably a documentation bug, since Ubuntu tries to use later versions of GTK in their projects. Also, GTK2 apparently hasn't been the default version of GTK used in mutter since 2010, going by this commit in their repository:
