bug#4539: 23.1; problem with attachments

[Art Werschulz <agw@dsm.fordham.edu>]

Running rmail, I visited a msg that had an attachment.  
I typed the "v" key, hoping to view the attachment.
I got the following error msg (from the *Messages* buffer):

rmail-mm-get-boundary-error-message: Malformed boundary; type: (multipart/alternative (boundary . =_alternative 0056AED705257627_=)); disposition: (inline); encoding: nil

If you like, I'll send you the entire message that produced the error.
Unfortunately, I can't generate a "minimal example", because on some
msgs the "v" command works and on some it doesn't; I am unable to
charactize a condition that makes the difference.
