We postulate the existence of self-generated normal current shot noise due to the long-lived voltage fluctuations in a hysteretic Josephson juntion. The resulting low temperature transition rates out of the (zero voltage) superconducting state are much larger than those arising from Johnson noise alone. Excellent agreement with experiments is then achieved at all temperatures. The problematic aspects of the theory are pointed out and discussed briefly.
