vm-8.0.12 breaks on unparseable addresses

[Manuel Carro]

In function vm-su-du-recipients (file summary.el), at the end, the call

    (vm-set-to-of m (mapconcat 'identity addresses ", "))

can fail (it failed for me) because the paremeter addresses can be bound to a string such as

"(Unparsable address -- Strange character \\; found: \";_^_>\")"

and mapconcat expects a list as second argument. The kludge I made was to convert it anyway to a list:

    ;; Patched by MCL for addresses which are not a list of addresses
    (vm-set-to-of m (mapconcat 'identity
        (if (eq (type-of addresses) 'string)
            (list addresses)
            addresses
        )
        ", "))

I could not test it thoroughly yet - and of course it is a kludge, but it points out to where the problem is.

Cheers,

Hi, if you can give us a sample of messages that generate the "unparsable address..." strings, we can see how to handle them. They should not be getting bound to the variable 'addresses'.

Cheers,

Unfortunately I am not using VM any longer, after maybe 10 years. I
have switched to GNUs. I have converted all my mailboxes, so I do not
have the original messages any longer.

Best,

Bug is present in VM 8.1.1.
Thanks for the workaround, MCL.

I can provide an example email header (part), which triggers the bug.
It was spam (received, then shot by spam-assassin); original domain / recipient replaced:

This is a problem with some versions of Gnu Emacs. The following work-around, contributed by Manuel Hermenegildo solves the problem. You can put it in your .emacs file, but remember to take it out when you upgrade your Emacs version.

;; Fixing temporarily the rfc822-addresses error
(defadvice rfc822-addresses (after rfc822-addresses-fixerror)
 "Fixes weird error return in rfc822-addresses."
 (setq ad-return-value
       (if (listp ad-return-value)
    ad-return-value
  (list ad-return-value)
  )))
(ad-activate 'rfc822-addresses)
