This is my fault, as I have apparently not tested if saving images with
custom classes work. The function reinitialize-all-types in
glib/gtype.lisp seems to be missing the code to re-register custom types
when the image is loaded. If you replace the current code with the
following, I think it should work:

(defun reinitialize-all-types ()
  (clrhash *lisp-type-to-type-number*)
  (clrhash *type-number-to-lisp-type*)
  (type-init) ; initialize the glib type system
  (mapc #'(lambda (type) 
            (register-type (car type) (cdr type)))
        *registered-types*)
  (mapc #'(lambda (type) 
            (apply #'register-new-type type))
        *registered-static-types*)
  (mapc #'(lambda (type) 
            (register-type-alias (car type) (cdr type)))
        *registered-type-aliases*))
