C-d displays duplicated parts

[Vladimir Volovich <vvv@vvv.vsu.ru>]

Hi,

i received a multipart/mixed message which contains a text/plain part
(the first one), and then five message/rfc822 parts; each of them has
the following headers:

Content-Type: MESSAGE/rfc822; name=Mailbox
Content-Description: Mailbox

When pressing C-d in a summary buffer, i get the following:

R  [ 303: Himanshu Gohel      ] <* mixed> Re: shared libs in teTeX
R      [  17: Himanshu Gohel      ] <1 text>

R          [  27: Thomas Esser        ] <6 text> Re: shared lib on Solaris and -Rpath

I.e. each message/rfc822 part is "duplicated". Is this correct?
