With Emacs from BZR (revision 110662) linked against the Motif toolkit
(version 2.3.4), I observe that after disabling the menu bar, the
frame doesn't have the correct height. The result is that the modeline
and the minibuffer are no longer visible.

Steps to reproduce:

   $ emacs -Q

   ;; Lisp Interaction Mode:
   (frame-pixel-height)
   608
   (frame-height)
   38
   (menu-bar-mode -1)
   nil
   ;; At this point, the X window shrinks by the height of the menu bar.
   ;; However, the bottom of the frame contents (containing modeline and
   ;; minibuffer) are no longer visible.

   (frame-pixel-height)
   608
   ;; Number of lines is _larger_ than before:
   (frame-height)
   40

It is reproducible with that WM.  My guess is that Xt filters out the ConfigureNotify from xfwm4 because of a bad timestamp or serial.

I have checked in a fix in the trunk.
