Well, I'm not sure about that, but I assume that the pixbuf in the
DrawingArea counts as a reference until you display a new pixbuf, and
the DrawingArea discards the old one. I noticed that the DrawingArea is
for custom widgets, so I have no idea how you use it...

You may want to write a small test loop for verify RefPtr's functioning
and check the memory usage during the program's runtime:

{
  Glib::RefPtr<Gdk::Pixbuf> mypixbuf;
  for (int i = 0; i < 100; ++i)
    mypixbuf = Gdk::Pixbuf::create_from_file(filename);
}

Regards.
