It looks like the problem is something to do with email package
behavior. Here is a test code to reproduce the problem:
----------------
from email import message_from_string
s = '''MIME-Version: 1.0
Content-Type: multipart/mixed; boundary="ABCDEFG"
Preamble
--ABCDEFG
A message without header
--ABCDEFG
Content-Disposition: inline
Another text with a header
--ABCDEFG--
'''
m = message_from_string(s)
for p in m.walk():
print p.get_content_type()
if p:
print p.get_payload(decode=True)
----------------
This program prints out like this:
multipart/mixed
None
text/plain
text/plain
Another text with a header
Note that 'A message without header' is not printed out.
If I remove 'If p:' and print the payload unconditionally, I get:
multipart/mixed
None
text/plain
A message without header
text/plain
Another text with a header
Here, the no-header part is printed out.
The patch of revision 7281 may have been over-protective against the
bug-id: 1099138 in message reconstruction part (line 327 in
http://mailman.svn.sourceforge.net/viewvc/mailman/branches/Release_2_1-maint/mailman/Mailman/Handlers/Scrubber.py?r1=7207&r2=7281
) but we may have to be paranoid against wired message like no-header
text. I believe well behaved MUAs won't generate no-header text parts.
(or, I believed ;-)
