Bug in GtkAda

["RasikaSrinivasan@gmail.com" <rasikasrinivasan@gmail.com>]

I have a piece of code that reads :
--------------------
      Gtk.Text_Attributes.Gtk_New(Special_Atr);
      Gdk.Color.Set_Rgb( Fg , 16#Ffff# , 0 , 0 ) ;
      Gtk.Text_Attributes.Set_Fg_Color
(Gtk.Text_Attributes.Get_Appearance(Special_Atr),Fg);
---------------

I am getting the following error while linking:

------------------------------------------
Sounds like a bug to me. Any ideas?
