No. Mutt follows the MIME decoding guidelines pretty strictly, and the
message you've outlined above has *explicitly* marked the text/plain
component as completely and fully equivalent to the subsequent
multipart/mixed component. Mutt considers the message's structure to
be essentially gospel for the purposes of rendering: if it's
displaying one of several equivalent alternatives, there's *no* point
in displaying *anything* from the other alternatives.
This is *usually* a good thing. A frustratingly common thing that is
done is that people will send emails where the html version has a
background graphic and extra graphics for a border and a header and
maybe a footer (and maybe more!), and these things are all really
irrelevant to the content of the message and would only be confusing
if they appeared listed in the pager. In these (rather common and
typical) cases, it is important that these other "attachments" are not
displayed when I display the text/plain component.
Now, it's quite possible to get *some* idea that there are other
attachments when in the *index* view rather than the pager view. You
can list the number of attachments with %X in the $index_format (how
mutt decides whether a MIME segment is considered a countable
attachment or not is described at length in the mutt manual, if you
want details on how to change that). You can also use %X in
$pager_format, to put the same information in the status bar along the
bottom.

>> the message contain more content is usefull.
Well, here's the thing: the MIME structure of the message *explicitly*
states that the other parts of the message DO NOT contain additional
useful content, but merely contain the exact same (read: "equivalent")
content in an alternative format. The message may be flat-wrong (it
wouldn't be the first message to be encoded in a broken way), but at
the moment, mutt doesn't have good ways of working around explicitly
erroneous MIME structures.
