I get this traceback:
---
  File "/home/florian/sources/cpython/Lib/email/__init__.py", line 40, in message_from_string
    return Parser(*args, **kws).parsestr(s)
  File "/home/florian/sources/cpython/Lib/email/parser.py", line 70, in parsestr
    return self.parse(StringIO(text), headersonly=headersonly)
  File "/home/florian/sources/cpython/Lib/email/parser.py", line 60, in parse

    self._cur.set_payload(EMPTYSTRING.join(lines))
  File "/home/florian/sources/cpython/Lib/email/message.py", line 311, in set_payload
    " payload") from None
TypeError: charset argument must be specified when non-ASCII characters are used in the payload

This is new in 3.4 since that's the first version which requires set_payload to provide a charset argument, imo message_from_string should figure that out from the message.
