Summary: Classifier UnicodeDecodeError on wrong transfer encoding

Initial Comment:
Running ``sb_imapfilter.py`` 1.0.1 seems to raise the following \
``UnicodeDecodeError`` when it comes across a mail with 7-bit content transfer \
encoding with 8-bit characters in it while classifying::

    Traceback (most recent call last):
    File "/usr/bin/sb_imapfilter.py", line 924, in ?
      run()
    File "/usr/bin/sb_imapfilter.py", line 914, in run
      imap_filter.Filter()
    File "/usr/bin/sb_imapfilter.py", line 785, in Filter
      self.unsure_folder)
    File "/usr/bin/sb_imapfilter.py", line 703, in Filter
      evidence=True)
    File "/usr/lib/python2.4/site-packages/spambayes/classifier.py", line 190, in \
chi2_spamprob  clues = self._getclues(wordstream)
    File "/usr/lib/python2.4/site-packages/spambayes/classifier.py", line 496, in \
_getclues  clues.sort()
  UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 1: ordinal not \
in range(128)

I'm attaching the mail which caused this.  I know it is not properly-formatted, but \
it is a legitimate mail produced by a popular MUA (Thunderbird 1.5).  Spam surely is \
worsely formatted

Someone talked about the same problem in the list: \
