[Spambayes] spambayes-1.0.3 fails

[Dmitry Karasik]

My fresh installation of sb_filter.py fails with the error. the file
'sample_mail' is a simple message, but the error is the same on every message
i've tested spambayes on. What can be wrong here?

$ sb_filter.py < sample_mail
Traceback (most recent call last):
