[Spambayes] AssertionError: hamcount <= nham

[Gerrit Holl]

Hi,

whenever I untrain a spam message accidantly trained as ham, by
database gets corrupted. I get the following error message:

Traceback (most recent call last):
  File "/usr/local/bin/sb_filter.py", line 203, in ?
    main()
  File "/usr/local/bin/sb_filter.py", line 199, in main
    action(msg)
  File "/usr/local/bin/sb_filter.py", line 132, in filter
    return h.filter(msg)
  File "/usr/local/lib/python2.3/site-packages/spambayes/hammie.py", line 109, in filter
    prob, clues = self._scoremsg(msg, True)
  File "/usr/local/lib/python2.3/site-packages/spambayes/hammie.py", line 38, in _scoremsg
    return self.bayes.spamprob(tokenize(msg), evidence)
  File "/usr/local/lib/python2.3/site-packages/spambayes/classifier.py", line 158, in chi2_spamprob
    clues = self._getclues(wordstream)
  File "/usr/local/lib/python2.3/site-packages/spambayes/classifier.py", line 395, in _getclues
    prob = self.probability(record)
  File "/usr/local/lib/python2.3/site-packages/spambayes/classifier.py", line 242, in probability
    assert hamcount <= nham
AssertionError

It makes no difference whether I use DataBase or pickle format.
Is there any solution apart from restarting the whole database?
This would mean I would have to restart the whole database after
each erroneous training. The latter is what I'm doing now :(

yours,
Gerrit.
