Hi,

Maybe I'm not doing this correctly, but right now I think gtk# doesn't
let you create a subclass of GLib.Object directly, because
Object.LookupGType() gets GType.Invalid from the default GType property
of GLib.Object. The attached patch adds a special case to let you
subclass successfully.

Just in case I'm missing something, here's my use case:

        public class NautilusExtension : GLib.Object,
		Nautilus.ColumnProvider,
		Nautilus.InfoProvider {

		static GLib.GType type;

		static NautilusExtension() {
			type = GLib.Object.RegisterGType (typeof (NautilusExtension));
		}

		public NautilusExtension() : base (type) {
		}
	}

Peter
