Summary: mboxtrain.py crashes on some mbox data

Initial Comment:
I'm trying to train a spam database and I'm
experiencing crashes with mboxtrain.py. I'm attaching
three mbox's (simplified to their offending e-mail)
that produce the crash. This happens with both CVS and
the last nightly build (tried both python 2.2 and
2.3a2). The message printed is:

This error still occurs with spambayes 1.0.4 and Python 
2.4.3.

The full error message for the final element in the stack 
trace now reads:
  File "/usr/local/lib/python2.4/email/Utils.py", line 222, 
in decode_rfc2231
    charset, language, s = parts
ValueError: need more than 2 values to unpack
