bug#10954: Emacs window shrinks automatically

[Walter Garcia-Fontes]

Ubuntu 12.04 Beta 1
Unity desktop environment

When starting Emacs without tool-bar and without menu-bar the windows
shrinks automatically to the size of one (text) line.

To reproduce, run current Unity desktop (5.4.0-0ubuntu2) and start
Emacs with the following command line:

emacs23 -Q --execute "(progn (tool-bar-mode 0)(menu-bar-mode 0))"

Note that both toolbar and menubar have to be disabled to see the
shrinking behavior.

FWIW, here's a video that illustrates the behavior:
