crash with invalid image map element

[SAITO Takuya]

Start emacs -Q, and evaluate below:

(insert-image
 (create-image
  "splash.xpm" nil nil
  :map (list (list
              (cons 'rect (cons (cons 0 0) (cons 300 300)))
              'id
              (list 'help-echo "id")))))

Then, emacs crashes if I move my mouse over the rectangle area. 

lookup-image-map's docstring and NEWS says that
image map's format is (AREA ID PLIST),
but isn't it (AREA ID . PLIST) ?
