gobject bug?

[tom <tom dbservice com>]

i created a fundamental object 'foo':

GType
foo_get_type (void)
{
	static GType type = 0;
	static const GTypeFundamentalInfo finfo = {
		G_TYPE_FLAG_CLASSED | G_TYPE_FLAG_INSTANTIATABLE | 
G_TYPE_FLAG_DERIVABLE | G_TYPE_FLAG_DEEP_DERIVABLE
	};

	if (!type)
	{
		static const GTypeInfo info = {
			sizeof (fooClass),
			(GBaseInitFunc) foo_base_init,
			(GBaseFinalizeFunc) foo_base_finalize,
			(GClassInitFunc) foo_class_init,
			(GClassFinalizeFunc) foo_class_finalize,
			NULL,
			sizeof (foo),
			0,
			(GInstanceInitFunc) foo_instance_init,
			NULL
		};

		g_type_init ();

		type = g_type_register_fundamental (g_type_fundamental_next (), "foo", 
&info, &finfo, 0);

		g_assert (G_TYPE_IS_FUNDAMENTAL (type));
	}

	return type;
}

foo *
foo_new ()
{
	g_log (G_LOG_DOMAIN, G_LOG_LEVEL_DEBUG, __FUNCTION__);
	return (foo *) g_type_create_instance (FOO_TYPE);
}

void
foo_destroy (foo * f)
{
	g_log (G_LOG_DOMAIN, G_LOG_LEVEL_DEBUG, __FUNCTION__);
	g_type_free_instance ((GTypeInstance *) f);
}

static void
foo_base_init (fooClass * g_class)
{g_log (G_LOG_DOMAIN, G_LOG_LEVEL_DEBUG, __FUNCTION__);}


static void
foo_base_finalize (fooClass * g_class)
{g_log (G_LOG_DOMAIN, G_LOG_LEVEL_DEBUG, __FUNCTION__);}


static void
foo_class_init (fooClass * g_class, gpointer class_data)
{g_log (G_LOG_DOMAIN, G_LOG_LEVEL_DEBUG, __FUNCTION__);}


static void
foo_class_finalize (fooClass * g_class, gpointer class_data)
{g_log (G_LOG_DOMAIN, G_LOG_LEVEL_DEBUG, __FUNCTION__);}

static void
foo_instance_init (foo * instance, fooClass * g_class)
{g_log (G_LOG_DOMAIN, G_LOG_LEVEL_DEBUG, __FUNCTION__);}

but if i do this:

main()
{
	foo *f = foo_new();
	foo_destroy(f);
	sleep(2);
	return 0;
}

i get:

(process:6270): foo-DEBUG: foo_new
(process:6270): foo-DEBUG: foo_base_init
(process:6270): foo-DEBUG: foo_class_init
(process:6270): foo-DEBUG: foo_instance_init
(process:6270): foo-DEBUG: foo_destroy

and thats all... why are the functions 'foo_class_finalize' and 
'foo_base_finalize' not called ?

thanks
tom
