Out of the hundreds and hundreds of bottles I have filled, I have had only 2 that "broke", and never any bottle bombs. You would have to prime to at least 4+ volumes before standard beer bottles start exploding. My guess, if it was just one bottle is the the bottle was weak or defective prior to filling, and the capping process weakened it further.
