Global menu broken after an update
I updated last (1am Nov. 26, 2012) and after that update the global menu is broken (i.e., I don't have global menu, instead the menu is shown on application windows). Moreover, when I right click on the desktop and select "Change Desktop Background", instead of "Appearance" settings, I get "System Settings" window (from which I can of course get to the appearance settings by clicking "Appearance").
This has happened on all three of my computers. All run Ubuntu 12.10 with unity.
