I'm unable to reproduce the bug.

Looking at the code, it seems like the following is returning
something...  something doesn't like:

(mapcar (lambda (i) (cdr (assoc 'viewer i)))
        (mailcap-mime-info "application/octet-stream" 'all))
=> (mailcap-save-binary-file)

(Only that yours includes the "open" thing, too.  Hm...

  string-match("" mailcap-save-binary-file)

[...]

  ido-set-matches-1(("/usr/bin/open %s" mailcap-save-binary-file) t)

Oh, you're triggering ido...  Right:

  gnus-ido-completing-read("Viewer: " (mailcap-save-binary-file "/usr/bin/open %s") nil nil nil nil)
  gnus-completing-read("Viewer" (mailcap-save-binary-file "/usr/bin/open %s"))

And ido doesn't work on symbols.

Fix in No Gnus.
