Summary: email.Generator traceback in forwarded msg

Initial Comment:
The SpamBayes sb_unheader app uses the email package
to dump out a copy of a message with user-specified
headers removed.  The email.Generator.Generator class is
barfing on the attached message.  I haven't had a chance
to look into it yet, but I suspect it's a problem in
the email
package, not the sb_unheader program.

Here's the traceback I see.  This is with a Python built
from CVS within the last couple days.

Works for me now as well.  Apparently the problem's been fixed...
Close?

This program works fine for me in Python 2.4 and 2.5:

import email

data = open('/tmp/newham').read()
msg = email.message_from_string(data)
print msg

Note that getting the str of the message will flatten it.
