[AUCTeX] Commands work but menu-bar not

[Finn Årup Nielsen]

I am experiencing the same problem with the speciel auctex-menu items
that do not open:

I have not seen any solution to the problem. My C-c C-c works, emacs -Q
doesn't help me. I have nothing of importance in my ~/.emacs except
(column-number-mode t) and custom-set-faces. I am using Ubuntu 10.10
(Maverick Meerkat) on the system that got the problem.
