I have the same problem that Andrea had.  If I use C-z (or M-x 
suspend-frame) then
(1) the window is minimized
(2) I can get it back by clicking on the emacs icon in the overview
(3) the menus work, but I cannot enter or edit any text any more.
  + I can even select checkboxes in the menus, and I can save the file 
from the "File" menu.
  + However, the text-entry area is frozen.
     - The scroll-bar will not scroll.
     - I can right-click on the text-entry area and change the current 
buffer from *scratch* to *Messages*, but the status bar is not updated 
to reflect the changes to *Messages*.  Interestingly, the 
'Lisp-interaction' menu item disappears, so I think that the buffer 
really is changed to *Messages*, but the buffer is just not displayed.

If I click on the minimize button on the frame decoration, emacs is 
minimized, and is usable after the emacs icon is clicked on again.

Using -Q makes no difference.

I'm using emacs 23.3 and gnome-shell 3.2.1.

Did you attempt to enter any text after you "got it back"?  If so, then 
perhaps this means that emacs 24 does not suffer from this problem.
