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: http://www.youtube.com/watch?v=_oKQjP8x_Os

(at first guess it seems more likely to be a Unity issue than an Emacs one)

The combination Gtk+ and Unity triggers a bug in one of them (not sure who has the bug).  If we set WM hints with base_height, one of them can't count and goes bananas.  I have checked in a fix in the trunk, which will be Emacs 24.  Please try it if you can.

In bug 10954, you said:

Is there any chance you can point me to the bzr revision with this fix?  What
is the likelihood that this could be backported to Emacs 23?  I would be
willing to sponsor this fix into Ubuntu 12.04 for Emacs 23 if it's relatively
easy to backport or if you could give me a hand with that.  I am highly
motivated by personal pain to make this work. ;)
