Not really in favour of this approach at all, there must be a better way to do
this that doesn't involve adding such checks to every single element.

Also, they're not really correct either, e.g.

  queue = GST_QUEUE (gst_pad_get_parent (pad));

might still throw a warning and possibly abort if get_parent() returns NULL,
which is arguably better than crashing, but still broken.
