[Python-apps-team] Bug#923077: pyzor: crashes on certain emails

[nijel]

Package: pyzor
Version: 1:1.0.0-3
Severity: normal

Dear Maintainer,

some tested emails make pyzor crash. I haven't collected the problematic
email, but I can probably do that as there is about one in a hour going
to my mail server and spamassasin complains with "internal error, python
traceback seen in response". If you have hints how to save the processed
email in that case, it would help.

The pyzor crashes with:

Traceback (most recent call last):
 File "/usr/bin/pyzor", line 408, in <module>
   main()
 File "/usr/bin/pyzor", line 152, in main
   if not dispatch(client, servers, config):
 File "/usr/bin/pyzor", line 237, in check
   for digested in get_input_handler(style):
 File "/usr/bin/pyzor", line 174, in _get_input_msg
   msg = email.message_from_file(sys.stdin)
 File "/usr/lib/python3.7/email/__init__.py", line 54, in message_from_file
   return Parser(*args, **kws).parse(fp)
 File "/usr/lib/python3.7/email/parser.py", line 54, in parse
   data = fp.read(8192)
 File "/usr/lib/python3.7/codecs.py", line 322, in decode
   (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x92 in position 1041: invalid start byte
