I'm getting a strange error whenever I try to export an org file, and I'm not sure how to track down the cause. It seemed to start when I upgraded to org 8.3.1, but it's hard to tell because this is the first time I've exported anything in a week or so.
(wrong-type-argument listp #("Test document" 0 13 (:parent (#1))))
org-element-set-contents(#("Test document" 0 13 (:parent (#0))))
I was able to figure out that the error only occurs when I have an org file with document data, e.g. a line like:
#+TITLE: Test document
When I remove that line as well as #+AUTHOR etc, then it exports fine. With that line it, it won't export to HTML, LaTeX, or text.
