Please don't. Switching to fontsets from fonts triggers
storing the contents of Text widgets as wide characters,
and, also, it is impossible to override a fontset with
a fontset.

Simply create a file in your home directory call ~/.gtkrc.ru

that looks like:

====
style "russian-fonts" {
# This may all have to be one big line. Not sure if we support multiline
# strings
       fontset = "-adobe-helvetica-medium-r-normal--10-*-*-*-*-*-iso8859-*,\
                  -cronyx-helvetica-medium-r-normal--11-*-*-*-*-*-koi8-r"
}

class "GtkWidget" style "russian-fonts"
====

And things will work pretty nicely. (You'll lose the 
Lucida in the metal theme unless you modify this
file when switching to that theme)

We actually should ship a set of gtkrc.(LOCALE) files
in the default GTK+ distribution. It is mostly a 
matter of coming up with the files and doing a little bit of 
automake work to get them installed in $(prefix)/etc/gtk/.
If you want to do this, go ahead, but please submit your
changes as a patch.
