bug#16565: 24.3.50; x-popup-menu just returns nil

[Michael Heerdegen <michael_heerdegen@web.de>]

Hello,

in emacs -Q, I eval the following:

--8<---------------cut here---------------start------------->8---
(defun foo (event)
  (interactive "e")
  (message "%s" (x-popup-menu event (mouse-menu-bar-map))))
 
(global-set-key
 [(meta control mouse-3)] ;just some free key
 #'foo)
--8<---------------cut here---------------end--------------->8---

Now, I hit M-C-mouse-3 somewhere.  The menu appears at the right place.
I select any item, and FOO messages "nil" instead of a list of events.
This is the bug.

However, when I redefine FOO so that it uses t instead of EVENT as first
argument of `x-popup-menu', it works as expected!

The problem seems to be system specific.  I see it on Debian Linux with
X, Drew Adams doesn't see it under Windows.

I use openbox, but the behavior is the same in an X session without any
window manager.


Regards,

Michael.
