gtk3 gem generates bindings at run-time. And it's occurred
when you touch methods or classes under the Gtk namespace
for the first time.

Your script works with the modification:

Gtk::ComboBoxText # Add this line or touch other methods or
                  # classes such as Gtk.check_version
                  # (Gtk::Version.or_later? is better than
                  # Gtk.check_version.)
class Gtk::ComboBoxText
  def set_names aL
    aL.each{|x| self.append_text x}
  end
end

Thanks,
