That usually means that you have misspelled an attribute. For example,
if you say Gtk.Wibbow instead of Gtk.Window, you'll get that error.
(It is actually a bad error message in that you are only looking up a
value, not creating one; is that only a Mono-only issue I wonder?)

As Jimmy says, we'd need to see the code to say more.
