Summary: classify trouble

Initial Comment:
I'm using sb_imapfilter.py from 1.0a6 on winXP with 
python2.3, 

It's been working fine for a while, but recently it's been 
giving an assertion error message when I try to classify 
my inbox.  Training seems to work fine.  The only thing I 
did out of the ordinary (I think!) was to erase all the 
emails in my spam training folder (roughly 1000 emails).  
Would this cause the problem?

I stuck in a quick 'print' statement for spamcount and 
nspam, nspam was 1293, spamcount was 1296..  

nspam is probably right, the imap web interface tells me 
that trained spam = 1293 and trained ham = 178
