Hi,

        I got a minor error when invoking `recover-this-file'.

        I saw a message from Emacs that I could recover a file.
        I switched to another buffer to check out something but
        didn't switch back when I invoked `recover-this-file' and
        got the error:

             Wrong type argument: stringp, nil

        Admittedly, this is minor and was my error in doing this but
        I think that Emacs should give a more informative error
        message.

        Thanks for your consideration.
