I've been known to make worse ones :-)

Doesn't seem to work the way it should. When I do this:

$model->set("type" => "Nspos::Db::Order");

the warning message looks like this:

Glib-GObject-WARNING **: value "((gpointer) 0x1c)" of type `GType' is invalid or out of range for property 
`type' of type `GType' at (...)

At least it's progress (it no longer talks about invalid numbers or
anything), but not quite there yet, I'd say.

(if you need anything further in order to debug this, please do ask)
