Do you really need to be that precise about the mutt file name?
Surely "/tmp/mutt-" is good enough...

(unless
    (catch 'found
      (dolist (arg command-line-args)
        (if (string-match "^/tmp/mutt-" arg)
            (throw 'found t))))
  (load "desktop")
  (dekstop-load-default)
  (desktop-read))
