Bug: html export fails after upgrading to 9.4 [9.4.1 (9.4.1-elpa @ /Users/jb/Library/Preferences/Aquamacs Emacs/Packages/elpa/org-20201212/)]

[Johannes Brauer]

Hi!

Trying to export a buffer to html containing

#+TITLE: Titel
* header

yields the error message:
apply: Wrong type argument: listp, #("Titel" 0 5 (:parent (#0)))

What can I do?

Johannes
