Sounds like the history indexes (generated with makedbz) are corrupted to
me.  Either that, or the message ID hash wasn't done right.  A grephistory
option to just print out the hash of the message ID would be useful here,
so that you could grep the history file for that hash and make sure that
part is working properly.

What could cause that, I have no clue.
