Summary: rfc822.Message.getdate('Date') exception

Initial Comment:
rfc822.Message.getdate('Date') will raise an IndexError
exception if the message header contains a null Date
line.

An example Python script that reproduces the exception
is attached.

As far as I know, this affects all versions of
rfc822.py.

The error is in rfc822.parsedate_tz which assumes
that its string argument is non-empty.

The first line should probably be:
	if not data: return None
