Comment 10 for bug 1130722

Hi Attila. The patch only enables the menubar when the "Gtk/shell-shows-menubar" xsetting is set. That means, only on desktop environments that show the menu bar outside of the application's window.

I don't think it is wise to check for the desktop environment to decide whether to show the menu bar in the window or not (we'd need to do that because we wouldn't want the menus in windows in gnome shell).
