For viewing, those are temporary files and will be deleted after
passing them to a viewer.  I had the same problem about xdg-open
and brought it up here years ago:

http://thread.gmane.org/gmane.emacs.gnus.general/68353

The solution I took then was to remove xdg-open from the mailcap
database, as described in the article.  You may want to add the
entries to the database[1] for the pairs of the content-types and
the viewers if Fedora doesn't provide them in the system mailcap
database.  To know what entries there are, do
`M-x load-library RET mailcap RET' and
`C-h v mailcap-mime-data RET'.

[1] An easy way is to have the ~/.mailcap file with the entries
    like the following:

application/pdf; /usr/bin/acroread %s
application/msword; /usr/bin/ooffice %s

    Note that whenever you edited the file you have to do
    `M-x mailcap-parse-mailcaps RET', or restart Emacs and Gnus.

I don't know.  Is it always empty for any attachment?

As for the case an empty file is saved, forward an example mail
to me if possible.
