Aha again! I guess I can free private members in the same method as well?

static void
neural_net_finalize (GObject *object)
{
  NeuralNet *nn;

  g_return_if_fail (IS_NEURAL_NET(object));

  nn = NEURAL_NET(object);

  g_free(nn->priv->weight_h);
  g_free(nn->priv->weight_o);
  g_free(nn->priv->bias_h);
  g_free(nn->priv->bias_o);
  g_free(nn->priv->filename);
  g_free(nn->priv);

  g_message("This is the finalize method and I've freed the instance
members!\n");

}

static void
neural_net_class_init (NeuralNetClass *klass){
	GObjectClass *gobject_class = G_OBJECT_CLASS (klass);
	gobject_class->finalize = neural_net_finalize;
	g_type_class_add_private (klass, sizeof (NeuralNetPrivate));
}

I think this looks ok, doesn't it? No, wait a minite.... What about the
parent? This class has GObjectClass as parent, how do I call it's finalize?

Thanks,
