+Subject: [PATCH] Move property and signal creation into _class_init()
+
+We must not add class interfaces after g_type_class_ref() has been called the
+first time. Move signal and property creation from pyg_type_register() into
+pyg_object_class_init(), and drop the hack of registering interfaces twice.
+
+This is a backport of commit efcb0f9fd for 2.28.x. This allows old pygtk
+applications to work with pygobject 2.28.x and glib 2.35.x.
