Hi!
When a spammer sends some invalid UTF-8 chars, we get this backtrace:

ProgrammingError: You must not use 8-bit bytestrings unless you
use a text_factory that can interpret 8-bit bytestrings (like
text_factory = str). It is highly recommended that you instead just
switch your application to Unicode strings.
See this bug in upstream bugtracker:
http://trac.edgewall.org/ticket/10033
Those changesets fix the problem:
http://trac.edgewall.org/changeset/9932
http://trac.edgewall.org/changeset/9933
This is pretty important since the package becomes useless because a
spammer just have to include some bad UTF-8 chars and the filter
becomes ineffective. Moreover, the training database could become
corrupted. Consider including this fix in the next point release.
