bug#8037: 24.0.50; Gnus article display of multiparts has become unusable

[David Kastrup]

If I read a multipart article containing a forwarded mail with
attachment, gnus is moving to the Date header of the included mail once
every second as soon as one goes into the article buffer in order to
move to the attachment.

This makes it utterly impossible to do any serious work.  I would guess
that this is a combination of Gnus trying to update the date header with
a "xxx minutes ago" hint and something with save-excursion or similar
going wrong.

I just pulled and rebuilt Emacs from the git mirror, and it did not
help.
