this is a pretty old report, but I would like to bring it back to life,
since I'm experiencing the same issue and I did some investigation.


I've found that in ox.el org-export--get-inbuffer-options function calls
org-element-map ... 'plain-text with a function that tries to use
org-element-set-element. But according to org-element.el, plaint-text
elements don't have a content and couldn't be set! So I believe this code is
buggy anyway. It's possible that this bug is not triggered in some (most)
configurations, because the code is not executed, but this doesn't make this
code correct anyway.

Unfortunately I'm not an expert in org-mode internals and don't have any
idea how to fix that. Looking forward for your help here.

Regards, Ilya.
