So one quick thought (I'm not sure if this helps) is that GtkTreeModel
is [natively in GLib terms] an interface, not an object.

Ordinarily a bunch of crazy casting takes care of this, but in the case
of working with GValues and GTypes, I'm not sure.

I don't think the problem is insurmountable. Worst case scenario we just
do an override code path for this (though if we keep doing that sort of
thing will aggregate cruft, which is why I discussed a possible code
generator solution in the previous email).

Ping me on IRC and we can talk more about it.

It would really help if you wrote a tinsy Example or Snapshot which
demonstrates the problem and added it to the branch and sent it along to
us... then we could see what you're trying to do.
