[O] Bug: Export breaks on documents with title [8.3.3 (8.3.3-26-ge92a06-elpaplus @ /Users/leafac/.emacs.d/elpa/org-plus-contrib-20160125/)]

[Leandro Facchinetti]

Hi, Org Mode contributors.

First, thanks for Org Mode. It changed my life!

I installed `org-plus-contrib' from `http://orgmode.org/elpa/' this
morning and got version `org-plus-contrib-20160125'.

Trying to export a file with a `#+TITLE:' set leads to the error:

    apply: Wrong type argument: listp, #("Writings" 0 8 (:parent (#0)))

Sample file:

    #+TITLE: Writings

The error happens regardless of the export backend.

I already ran `emacs -q' and the problem persists.

I appreciate any help debugging.
