This means that your database is corrupt.  If you are using dumbdbm (you
will have hammie.db.dir and hammie.db.dat files), you should change to
using a pickle/pybsddb.  See the message from Skip (about 4 messages
ago) about where to find information about doing this.

In either case, you will need to retrain your database.

Note that:
  1.  We've (just) checked in a change that means that when this occurs
an error will also be printed (so that you are aware of it, rather than
just finding another header).
  2.  If you're not using dumbdbm, and you find that your database is
regularly becoming corrupted, then we need to figure out why this is, so
please let us know if this is the case.
