[Spambayes] Message Causes Spambayes to Crash

[rruth at computer.org]

The main MySQL e-mail list  (digest version) always causes Spambayes to crash. 
 Although it looks like the fault is in Generator.py.  As soon as I delete the 
MySQL digest message, Spambayes runs normally.

With a MySQL digest message in my inbox (and not deleted):

/usr/bin/python $HOME/spambayes/mboxtrain.py -d $HOME/.hammiedb -g 
$HOME/Mail/NewSoftware -g $HOME/Mail/ham-train -s $HOME/Mail/spam -g

    raise TypeError, 'string payload expected: %s' % type(payload)
TypeError: string payload expected: <type 'list'>


And after I delete the MySQL digest message:

/usr/bin/python $HOME/spambayes/mboxtrain.py -d $HOME/.hammiedb -g 
$HOME/Mail/NewSoftware -g $HOME/Mail/ham-train -s $HOME/Mail/spam -g 
$HOME/Mail/inbox

Training ham (/home/richard/Mail/inbox):

  Trained 21 out of 21 messages                
Training spam (/home/richard/Mail/spam):
  Reading as MH mailbox
  Trained 12 out of 12 messages                


Any  idea on how to fix this problem with MySQL list digest messages?
