Comment 26 for bug 1153350

Commited fix is to revert commit #3196 in Unity.
Commit #3196 was: "Don't attach the menus to an invisible menubar."

(see http://bazaar.launchpad.net/~unity-team/unity/7.0/revision/3196#services/panel-service.c)

Don't know why is was done in the first place, there are not much comments on this commit...
