problem with auto-preview/use of new font settings in control-center

[Simos Xenitellis <simos74 gmx net>]

Short description: The Control Center allows to change the font used in
GNOME applications. This does not work in specific locales like
el_GR, ru_RU, tr_TR. However, it works with C, es_ES, fr_FR, it_IT, zh_TW
and so on.

I am using the latest GNOME environment by Red Carpet.

To verify which locales are problematic

	% setenv LANG C
	% setenv LC_CTYPE el_GR
		(we use LANG=C and LC_CTYPE=el_GR because if all were
		el_GR, you would be confronted with Greek fonts.
		If you are brave enough, "setenv LANG el_GR". Same result.
	% gnomecc   	(GNOME Control Center)
	From here choose
		Desktop/Theme Selector/User Font
		Activate: Use custom font.
		Activate: Auto Preview
		Choose another font, for example arial with font size
		18.

		As you will see, the preview window does not show the
		newly selected font.

		Ctrl-Q to exit.
	% setenv LC_CTYPE C
	% gnomecc

		Try as above, it works ok.


	To sum up, I found that
		el_GR
		tr_TR
		ru_RU

		are problematic

	while
		C
		es_ES
		zh_TW
		it_IT
		fr_FR

		are ok.

	I did not try more locale variables.

I would like some initial comments before submitting a bug report to
bugzilla.gnome.org.

Thanks in advance,
