I think the GstObject.lock should be a GRecMutex. The problem is that
gst_object_dispatch_properties_changed() walks a chain of
obj->parent->grand_parent->...->root, where we need to avoid to lock parent in
some cases.
Now gst_object_set_parent() which should call g_object_notify_by_pspec() does
not know whether parent is locked or not.

Should we add a gst_object_set_parent_locked() which would unlock parent and
call gst_object_set_parent() - not pretty either :/
