When I rewrite in emacs.scm `read-dialog` from

(define (read-dialog prompt)
  (symbol->string
   (invoke (as <frame> (window-frame)) 'ask prompt)))

to

(define (read-dialog prompt)
  ;; (symbol->string
  (invoke (as <frame> (window-frame)) 'ask prompt));;)

result is

#|kawa:2|# Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
