That's nice and it's certainly the behaviour one would expect. I'm not
sure though if there are other references to pixbuf_. While the pixbuf_ is
being assigned new memory in the second load_image(new_image) call, it
(the pixbuf) is already being displayed in a DrawingArea. Does that count
as a reference? Other than that, there is no other RefPtr pointing to the
same pixbuf_.
