Now I have the completion in shell also, for this
`shell-command-completion' have to be redefined.

--8<---------------cut here---------------start------------->8---
(defun shell-command-completion ()
  "Return the completion data for the command at point, if any."
  (let ((filename (comint-match-partial-filename))
        (args (split-string
               (buffer-substring-no-properties
                (point) (save-excursion (shell-backward-command 1) (point))))))
    (if (and filename
             (save-match-data (not (string-match "[~/]" filename)))
             (and (string= (car args) "sudo")
                  (string= filename (cadr args))))
        (shell--command-completion-data))))

HTH, though the crash happening above should not happen.
