I do not see how it is related.
Do you see the error with your config or with clean Emacs?

Oops. Another side-effect of `buffer-file-name'. Fixed now.

Done.

I am not sure how to test this part.
I instead documented the caveats in `org-export-copy-buffer' docstring
and in the `org-html-format-latex'.

Though maybe the code in `org-html-format-latex' should be factored out
into a separate macro like `org-export-with-persistent-buffer-copy'. The
macro will accept buffer name as an argument and do everything necessary
to not keep the `buffer-file-name' around.
