bug#10102: emacs 24 read-file-name bug?

[Lachlan Deck]

Hi there,

In emacs 24 the following 'message' produces the empty string if you just hit 
enter at the mini-buffer prompt. In emacs 23, the 'guess' variable is printed 
as expected.

Is this a known bug?

(let* ((default-directory "~/path/to/project/")
      (guess (concat default-directory ".foo"))
      (file (read-file-name
             "Foo: "
             (file-name-directory guess)
             guess
             nil
             (file-name-nondirectory guess)
             )))

 (message file))
