Alright, the pool is NULL because it has never been created, because
negotiation failed. But for some reason (an asynchronous state change), the
task is re-started after it has been paused. But because of bug #691986, the
NEED_RECONFIGURE flag is not longer set, and it tries to create the buffer
without having caps set, and so it crashes!
