This bug seems to have been fixed for 11.10, so I cannot reproduce it anymore. From memory, I can provide the following:
1. Install Ubuntu 11.04, change the gtk theme to something else. I think Clearlooks showed the problem.
2. The unity global menu bar's GTKMenuItems should look the same as if they were in a GTKMenuBar in a window or in the gnome-globalmenu project's global menu applet.
3. The unity global menu bar's GTKMenuItems look different than they would if they were in a GTKMenuBar in a window or in the gnome-globalmenu project's global menu applet (see picture I originally attached).
