[Python-apps-team] Bug#478269: Incompatible db version is not a spambayes bug

[Jeff Epler]

The basic error seems to be
    Invalid argument -- /var/spambayes/spambayes.messageinfo.db: unsupported
    hash version: 9

This is a duplicate of the (closed) bug #469770.  That bug suggested:

    The Debian version of Python 2.5 was originally built using Berkely DB
    4.6. Due to problems with DB 4.6, this was reverted to DB 4.5 in Debian
    package 2.5.1-7. However, databases created (or modified?) by DB 4.6 are
    not usuable by DB 4.5; a common indicator is this exception:

        bsddb.db.DBInvalidArgError: (22, 'Invalid argument --
        /some/file/name: unsupported hash version: 9')

    Note that you may not have explicitly used the bsddb extension, as other
    modules (such as anydbm and shelve) may use bsddb.

    To restore Python 2.5 access to your existing DB 4.6 file, you need
    to install two packages: db4.5-util and db4.6-util. Then, to recover
    the file "example.db", use the following sequence of commands, noting
    carefully the distinction between 4.5 and 4.6:

    $ mv example.db example.db.db46
    $ db4.6-dump example.db.db46 | db4.5-load example.db

(I don't know if this advice is still applicable; it will be difficult to
follow, as neither named package is available in Debian Jessie)

In any case, I recommend closing this bug as a duplicate of #469770
