Just for the record:

I have found that it's eventually useful to try to look at Gtk+
"official C" documentation when coding with a binding (not only with
Gtk2Hs, but also Gtk#, PyGtk, etc).

(Also, it seem the second argument should be "Maybe GC" as the C
documentation says it could be a NULL value.)
