As a side note, you can load and scale immediately by using
gdk_pixbuf_new_from_file_at_scale(). This will be more efficient for
some image types.

Yours is a more generic question than whether you need to do it for
iconviews or not. It has to do with how to manipulate a GObject instance
in liststores/treemodels. In general, any time you set a GObject in a
model, this will own a reference. So, if you don't need your reference,
you can remove it.
On the other way around, when you retrieve a GObject from a model,
you'll own a reference that you need to remove when you are done with
the object.
