I was wrong here; there's no race condition, but it depends on the order
of mode activation. If you *first* enable global-ede-mode and then
semantic-mode, the Development menu will be disabled. So to be clear:
the above recipe is false; you have to do 'M-x global-ede-mode' first,
and then do 'M-x semantic-mode'.

It actually seems that the menu entry that is displayed is the one which
was activated last.

As Nikita already wrote in his initial report, the text-mode menubar
(M-x tmm-menu) has the same problem, though I don't if it uses the same
code as the "Global Menu" popup.
