As I said, gst_pad_get_parent() takes the pad object lock. It then refs
the _parent_, not the pad (you're correct, of course, that reffing the
pad again isn't needed - it doesn't do that).

Perhaps Wim can clarify - what cases require gst_pad_get_parent(), and
where is it safe to only use GST_PAD_PARENT()? Is Stefan's patch
