This error occurs when there's a problem loading the (pickled) database -
from the traceback, the 'messageinfo' one.  There are a couple of likely
causes:

 1. The file that the config files points to as the 'messageinfo' database
isn't a pickle, it's a bsddb db.  In this case the [Storage]
persistent_use_database ("Use database for storage") option needs to be set
to "dbm", or the file needs to be removed to start with a fresh (empty)
pickle.

 2. Something has gone wrong with the messageinfo pickle (i.e. when it was
being saved).  CVS now saves to a temp file first to avoid this, but 1.0
doesn't, so it could be the case.

Otherwise, this might be a SpamBayes bug that's causing it to try and load
the database as a pickle when it has been told not to (I hope not, but it
could be...).
