[ruby-gnome2-devel-en] Problem clearing elements from Gtk::ComboBox

[DaVinci <da...@es...>]

 Hi everybody.

 I have a little problem with version 0.15 of Ruby-Gtk2. Look at this
 class:

---------------------------
class BotonOpciones < Gtk::ComboBox
        def initialize(valores=3Dnil, inicial=3Dnil)
                super()
                aniadir_opciones(valores, inicial) if valores
        end

	# Esta funci=F3n est=E1 separada para que se puedan cambiar las
	# opciones todas las veces que sea necesario.
        def aniadir_opciones(valores,
		inicial=3Dnil)
		=09
		model.clear	# HERE IS THE PROBLEM!!!!!!
                @valores =3D valores
                @valores.each do |v|
			append_text(v)
		end
		if inicial
			poner_valor(inicial)
		end
	end
end
--------------------------------------------------

 When I try "model.clear", get the error:

 	`aniadir_opciones': undefined method `clear' for
	#<#<Class:0xb6750eac>:0xb66c6f90 ptr=3D0x85c6790> (NoMethodError)

 It worked until 0.14 version, and API documentation doesn't show any
 deprecation or change.

 Is this a known problem? Perhaps a bug?

 Thank you.
