rfc822.AddressList incorrectly handles empty address.
"<>" is converted to None and should be "".
AddressList.__str__() fails on None.
I got an email with such an address and my program
failed processing it.
Example:
>>> import rfc822
>>> rfc822.AddressList("<>").addresslist
[('', None)]
>>> str(rfc822.AddressList("<>"))
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/lib/python2.1/rfc822.py", line 753, in __str__
return ", ".join(map(dump_address_pair,
self.addresslist))
TypeError: sequence item 0: expected string, None found
[His solution: in the internal routine AddrlistClass.getrouteaddr(),
initialize adlist to "".]
