Comment (by nickm):

 So the consensus diff is supposed to include the starting hash and the
 ending hash.  If the consensus diff is not corrupted, and if we're
 checking the starting hash, then applying the diff should result in the
 ending hash.

 So probably one of those conditions is violated?  Maybe we're not checking
 the starting hash, or maybe we're applying the diff to the wrong thing, or
 maybe the consensus diff is corrupted.

 The fact that this happens over and over makes me wonder if we're
 downloading the diff over and over.  If we are, then maybe there's a
 problem with the initial consensus that we're applying it to?
