Subject: 25.1.90; Stale menu items after switching to a different major mode
 (or visiting a buffer)
Date: Mon, 5 Dec 2016 00:45:52 +0200

1. Start 'emacs -Q', and

- In *scratch*, M-x ruby-mode (or python-mode, or probably many others)

OR

- C-x C-f, visit a Ruby file (or, again, probably any other file)

2. See the "Lisp Interaction" menu disappear, and "Ruby" manu appear.

However, the contents of that menu are exactly the same as what was in
"Lisp Interaction".

If I toggle menu-bar-mode off and on, the menu obtains the correct
contents.

I'm also seeing a problem the menu added by a minor mode which appears
blank at first (which is fixed the same way), but let's tackle the more
obvious problem first.

Looking at older versions, the problem is present as far back as 24.3
(with python-mode; ruby-mode didn't have a menu then).

So this is probably caused by a library change, like the GTK version I
have installed.
