+	* atk/atkutil.c:
+	Changed calls to g_type_class_peek() to g_type_class_ref() where
+	it makes more sense, and in other places check for a non-null
+	klass return before trying to call class methods.  This prevents
+	SEGV if no Atk-implementation library has been loaded.
+
+	* atk/atkobject.c:
+	Fixed gtk-doc warning.
