Ugh. Perhaps Bogofilter should provide some protection against this kind
of mistake. Would it make sense to complain when a message that has never
been registered is being unregistered? (It would be quite easy to
implement imho: compute a hash of token list generated from the message,
turn it into a quasitoken like .MSG_COUNT, increment its count during
registration, check and decrement it during unregistration.)

This is quite likely.
