Daniel: i can't remember the exact scenario (i filled this bug 2 years
ago !)
after having a look back at email.message.Message.get_payload, i
remember the problem: the decoding errors are silented by the method and
you have no way to know if the decoding has been successful or not.
to find my malformed email i had to patch the module like that
(basically just removing the try/except blocks):
<patch>

+ return sfp.getvalue()
# Everything else, including encodings with 8bit or 7bit are
returned
# unchanged.
return payload
</patch>
once again, the behaviour is documented, so it's not really a bug.
but it caused me a lot of trouble (and it does not conforms very well to
"Errors should never pass silently.":)
but i guess applying such a patch could potentially break number of
client code so... is it worth the change?
