wrong type argument with latest org and latest emacs

[Colin Baxter <m43cap@yandex.com>]

I'm sending this to emacs.orgmode and emacs.devel lists.

With the latest emacs:

(1) emacs -q <RET>
(2) M-x org-version <RET>
    --> Org mode version 9.5.4 (release_9.5.4-3-g6dc785
(4) C-x C-c --> emacs closes with no messages

(5) Repeat (1)
(6) In scratch buffer load latest org-mode by eval
   (add-to-list 'load-path (expand-file-name "/path/to/git/org-mode/lisp"))
(7) M-x org-version <RET>
    --> Org mode version 9.5.4 (release_9.5.4-608-g080462
(8) C-x C-c --> emacs closes with error message
    --> Wrong type argument: stringp, (wrong-type-argument stringp nil)

Debugging further reveals:

Debugger entered--Lisp error: (wrong-type-argument stringp (wrong-type-argument stringp nil))
  format-message((wrong-type-argument stringp nil))
  apply(format-message (wrong-type-argument stringp nil))
  error((wrong-type-argument stringp nil))
