Summary: Unhandle exception in Message.get_content_charset()

Initial Comment:
Message.get_content_charset() can encounter an
unhandled exception "(TypeError: unicode() argument 2
must be string, not None") when charset is None.  This
can can only occur when the call to
email.Message.Message.get_content_charset(self,
failobj) itself returns None, but, not being acquainted
with the email package, I don't understand the
circumstances which can cause this situation.

Regardless, when charset is None, the call to unicode()
will throw the TypeError exception.  The attached patch
recognizes this as a valid failure case such that
failobj will be returned.

If it's not too much trouble.  I'd love to have a test case
in the email package for the TypeError exception.  If you
can't, no worries.

Sorry, I don't.  Those messages were unshunted as a result
of my fix.  I could try to instrument a collection mechanism
by trapping that exception and storing a copy of the
offensive message, however.  Would that still be useful?

Is there any possibility that you have a sample message that
exhibits this problem?  I would /really/ like to add a test
case for this to the email package, which is where the patch
really belongs.

Thank you!  I just fixed in CVS.
(I'd rather make it bare except ...)
