Hello,
I just tried building the newest emacs master branch (git cloned
repository), running Ubuntu 12.04 GNU/Linux system.
I made a mistake of adding option "--enable-gcc-warnings" to
"./configure" (not anticipating it would add option -Werror :-). The
complete list of options to ./configure: "--prefix=/usr/local
--program-suffix=-git.master --enable-check-lisp-object-type
--enable-link-time-optimization --enable-gcc-warnings
--with-x-toolkit=gtk3 --with-x".
The file "src/gtkutil.c" gave the following warning:
gcc -std=gnu99 -c -Demacs -I.

I found GTK3 API documentation and within couple of minutes of reading
quickly applied the following fix:

return fontname;
This fixed the compilation for my Ubuntu 12.04 machine (gtk3 seems to
be version 3.4.2). I tried selecting font (by [SHIFT] +
[LEFT-MOUSE-BUTTON]), and the new font selection widget worked for me.
Note that I have never before done programming with GTK API, so you
might review this with some care, and check the compatibility with the
supported versions of GTK3 if you choose to apply this kind of fix to
future versions of Emacs.
Best regards and thanks for everybody's work for fabulous text editing
environment (or whatever emacs should be called),

I guess we have to conform then. I fixed this in a backwards compatible fashion.
The chooser dialog is a huge step backwards in usability. It is larger, it is
slower (esp. X over a slow link), it emits warnings to the console when it
can't render a font, like this:
(emacs:9374): Pango-WARNING **: failed to choose a font, expect ugly output.
engine-type='PangoRenderFc', script='latin'
(emacs:9374): Pango-WARNING **: failed to choose a font, expect ugly output.
engine-type='PangoRenderFc', script='common'
and it uses a red X for minus on some themes (see screenshot) which is
confusing. But hey, this is "progress".

Hello Jan,
Sorry for late reply, I just now noticed your email by searching my
overpouring inbox after witnessing the change in git repository as a
result of performing "git pull".
After my initial email report I compared unpatched version of emacs
with older font selection dialog (running in a different machine), and
also wondered about the usability degradation. I wish things will
quickly improve in GTK3 front so that I will not have to feel guilty
for lowering usability of Emacs with my report... ;-)
