Initial Comment:
Both messages in the attached file cause both 1.0a7 and
1.0b1 to die with the following output:

This is on a pretty vanilla Red Hat 9 system running
Python 2.2.  If you need any more info, let me know.

For the short term, I've checked in the fix that was applied
to sb_filter (in 1.0rc1) to sb_mboxtrain, which should fix this.

For the medium term, we'll (after 1.0) switch sb_filter and
sb_mboxtrain over to using the spambayes Message class (like
sb_imapfilter, sb_server and sb_pop3dnd) so that fixes like
this only need to be applied in one place.

For the long term, Python 2.4's email package (2.5, IIRC)
handles malformed messages much more gracefully.  This will
be used for binary releases, and will work with people
running the source with Python 2.4.  We might bundle bits of
the code for 2.2/2.3 users; I'm not sure.

I found this too, and, with a little experimentation, found
that it was the Content-Type line in the email that made the
difference.

Something does not like the following:
Content-Type: text/html;
        boundary="--1474828438272566"

If you change that to 
Content-Type: multipart/alternative;
        boundary="--1474828438272566"

It processes without errors.

I get the same error on a FreeBSD system running Python 2.2.2.  
It occurs in both 1.0a7 and 1.0b1.1. 
 
I winnowed down my corpus of spam until I found the message 
that was causing the bug.  Deleting this message from my spam 
mailbox eliminated the error.  You can get a copy of the 
offending spam here:

I got what appears to be the same error with a different
presentation.  The below came from SpamBayes POP3 Proxy
Version 1.0b1 (April 2004), running on Windows 2000
Professional:
