My guess is it's a bug in dumbdbm.  I strongly suggest you either install
PyBSDDB (aka bsddb3) or switch to the pickle format instead of the db
format.  Dumbdbm is meant to be a last resort sort of fallback for the
anydbm/shelve modules.  I don't think anyone here has tested Spambayes using
it, because essentially every platform has available some better db file
implementation available.  I wouldn't rely on it for something as important
as your email.
