It was a bug occuring a few versions ago.  
It was corrected or at least inactive in emacs-version "24.3.1" and a
couple of previous versions.

Just resizing the emacs window was enough for it to recompute and
redisplay the geometry correctly.

Perhaps adding something like:

    (let ((h (frame-parameter (selected-frame) 'height))
          (w (frame-parameter (selected-frame) 'width)))
      (set-frame-width  (selected-frame) (1- w))
      (set-frame-height (selected-frame) (1- h))
      (set-frame-width  (selected-frame) w)
      (set-frame-height (selected-frame) h))

at the end of ~/.emacs ?
