i didn't check in the modifications yet, but your patch is exactly like 
the experimental one i wrote before and i think it's time to check it in.

so i suppose that we should definitely check in the gtk_reparse_all() 
patch so that gtkrc file is reloaded every time a question is diplayed.

maybe the localechooser patch has to be extended to solve similar issues 
for arabic and persian languages?

Note that the standard gtkrc file will have to have this structure

gtk-theme-name = "current theme"
gtk-font-name="current font"

We must  preserve the theme line when we overwrite the gtkrc file, so i 
think the localechooser patch should be modified like this or similar

# store the current theme name to restore it later
CURRENT_THEME=$(grep gtk-theme-name /etc/gtk-2.0/gtkrc)

# set the primary font accroding to $LANGUAGE
if [ "$DEBIAN_FRONTEND" = "gtk" ]; then
    case "$LANGUAGE" in
	ja)
	    echo 'gtk-font-name = "Sazanami Gothic 12"' >  /etc/gtk-2.0/gtkrc
            ;;
	zh)
	    echo 'gtk-font-name = "AR PL ShanHeiSun Uni 12"' > /etc/gtk-2.0/gtkrc
            ;;
	ko)
	    echo 'gtk-font-name = "UnDotum 12"' > /etc/gtk-2.0/gtkrc
            ;;
    esac

    # restoring the current theme information
    echo $CURRENT_THEME >> /etc/gtk-2.0/gtkrc
fi
