heh, I just ran into exact same issue w/ v4l2sink.  And even in a pipeline
without a tee, since gst_mini_object_free() increments the refcnt before
calling finalize function (which puts buffer back on queue making it available
to thread calling _buffer_alloc())

for now I just check:

    if (buf->parent &&
        (GST_BUFFER_DATA (buf) == GST_BUFFER_DATA (buf->parent)) &&
        (GST_BUFFER_SIZE (buf) == GST_BUFFER_SIZE (buf->parent))) {
      ....
    }

it's a bit ugly.. it might be nice to have a better API to tell me the same
thing, that it's a sub-buf w/ offset of zero and size equal to original buffer.
 Or even better if it was somehow transparent..
