Problem with imenu.el

I think there's a problem with Imenu when a buffer has no functions in it. I know Imenu is newly ported to XEmacs (thanks Hrvoje!) so there may be some rough edges. Mostly it works pretty well (I've been updating the python-mode.el support). Here's how to reproduce. Start up a vanilla XEmacs with the menubar on, and be sure the imenu library is loaded. Visit an empty Emacs-Lisp buffer, and run imenu-add-to-menubar (type "IM-Elisp" at prompt). You should now see a menu item that reads "IM-Elisp". Try to pull this menu down and you will get an error menu name (first element) must be a string: (nil) This is because the imenu-create-index-function returns nil, which triggers the second or-clause in imenu--make-index-alist, thus eventually setting imenu--index-alist to '(nil). In Emacs, this return value seems to tell the menu posting code (where ever *that* is ;-) not to post a menu item. In XEmacs, however this causes an error. I am unsure what the right thing is to return in XEmacs, so I can't supply a fix. Thanks, -Barry
