reference count not freed in dispose?

[Yu Feng <fengy indiana edu>]

Hi,

I was reading gtkcellrendererspin.c
and saw:

static void
gtk_cell_renderer_spin_finalize (GObject *object)
{
  GtkCellRendererSpinPrivate *priv;

  priv = GTK_CELL_RENDERER_SPIN_GET_PRIVATE (object);

  if (priv && priv->adjustment)
    g_object_unref (priv->adjustment);

  G_OBJECT_CLASS (gtk_cell_renderer_spin_parent_class)->finalize (object);
}

Isn't it suggested that the reference counts should be freed in dispose
method in GObject's document?
