Summary: BASE64 attachments barfing

Initial Comment:
When testing MIME attachments I get the following error
which occurs using arch to convert a mailbox or when
posting to the archive:

Pickling archive state into
/usr/local/mailman/archives/private/opsarchtest/pipermail.pck
Traceback (most recent call last):
  File "bin/arch", line 160, in ?
    main()
  File "bin/arch", line 148, in main
    archiver.processUnixMailbox(fp, Article, start,
end)
  File
"/usr/local/mailman/Mailman/Archiver/pipermail.py",
line 545, in processUnixMailbox
    m = mbox.next()
  File "/usr/local/lib/python2.2/mailbox.py", line 34,
in next
    return self.factory(_Subfile(self.fp, start, stop))
  File "/usr/local/mailman/Mailman/Mailbox.py", line

    return mailbox.scrub(msg)
  File "/usr/local/mailman/Mailman/Mailbox.py", line

    return self._scrubber(self._mlist, msg)
  File
"/usr/local/mailman/Mailman/Handlers/Scrubber.py", line

    url = save_attachment(mlist, part, filter_html=0)
  File
"/usr/local/mailman/Mailman/Handlers/Scrubber.py", line
217, in save_attachment
    decodedpayload = msg.get_payload(decode=1)
  File "/usr/local/mailman/pythonlib/email/Message.py",
line 177, in get_payload
    return Utils._bdecode(payload)
  File "/usr/local/mailman/pythonlib/email/Utils.py",
line 71, in _bdecode
    value = base64.decodestring(s)
  File "/usr/local/lib/python2.2/base64.py", line 44,
in decodestring
    return binascii.a2b_base64(s)
binascii.Error: Incorrect padding

I've narrowed this down to HTML attachments that
include tables. I've attached a mbox that will give
this error when used with arch. This only happens when
base64 is used.

I've also found that even when messages with HTML
attachments are archived, clicking on the attachment
doesn't display the page but the source instead. Or in
some cases it can be garbage. I can supply more info on
this if you wish.

Whoops. Attached the html file which was used as attachment
instead of the mbox file....
