I am using emacs-snapshot on Ubuntu 11.04.
In some of the emacs modes, like Auctex and ESS, the menus have no contents, i.e. in Auctex when I click on the Preview, Latex, or Command menus, a small empty rectangle appears. The standard menus (File, Edit, Options, Buffers, Tools) have regular contents.
This has occurred around the same time as updating from Ubuntu 10.04 to 11.04, but I am not sure if they are related.
The problem does not occur using emacs-23.
How can I get the menus back?
