Bug: org-export-as

Hi,

I'm trying to debug the package org2nikola, which works on emacs-24.5
but not on >emacs-25. What I'm trying to see is why the title is
exported when using >emacs-25 but not when prior versions. For what I've
being testing, it doesn't seem related to the package but to org-mode or
emacs. I'll explain why I think this. An example text I want to export would be:

  ,---
  | * TODO Testing                                                    :test:
  |   Nullam eu ante vel est convallis dignissim.  Fusce suscipit, wisi nec
  |   facilisis facilisis, est dui fermentum leo, quis tempor ligula erat
  |   quis odio.  Nunc porta vulputate tellus.  Nunc rutrum turpis sed pede.
  |   Sed bibendum.  Aliquam posuere.  Nunc aliquet, augue nec adipiscing
  |   interdum, lacus tellus malesuada massa, quis varius mi purus non odio.
  |   Pellentesque condimentum, magna ut suscipit hendrerit, ipsum augue
  |   ornare nulla, non luctus diam neque sit amet urna.  Curabitur
  |   vulputate vestibulum lorem.  Fusce sagittis, libero non molestie
  |   mollis, magna orci ultrices dolor, at vulputate neque nulla lacinia
  |   eros.  Sed id ligula quis est convallis tempor.  Curabitur lacinia
  |   pulvinar nibh.  Nam a sapien.
  `---

I would execute the function `org2nikola-export-subtree' in the
header. More or less, this function would guide us until the next
function with the above text, but not the header, marked as a region:

  ,----
  | (org-export-as 'html t nil t)
  `----

In emacs-24.5 this function returns:

  ,----
  | <p>
  | Nullam eu ante vel est convallis dignissim.  Fusce suscipit, wisi nec facilisis
  | facilisis, est dui fermentum leo, quis tempor ligula erat quis odio.  Nunc porta
  | vulputate tell us.  Nunc rutrum turpis sed pede.  Sed bibendum.  Aliquam posuere.
  | Nunc aliquet, augue nec adipiscing interdum, lacus tellus malesuada massa, quis
  | varius mi purus non odio.  Pellentesque condimentum, magna ut suscipit hendrerit,
  | ipsum augue ornare nulla, non luctus diam neque sit amet urna.  Curabitur vulputate
  | vestibulum lorem.  Fusce sagittis, libero non molestie mollis, magna orci ultrices
  | dolor, at vulputate neque nulla lacinia eros.  Sed id ligula quis est convallis
  | tempor.  Curabitur lacinia pulvinar nibh.  Nam a sapien.
  | </p>
  `----

In >emacs-25 this function returns:

  ,----
  | <div id="outline-container-org1ce23b7" class="outline-2">
  | <h2 id="org1ce23b7">Testing</h2>
  | <div class="outline-text-2" id="text-org1ce23b7">
  | <p>
  | Nullam eu ante vel est convallis dignissim.  Fusce suscipit, wisi nec facilisis
  | facilisis, est dui fermentum leo, quis tempor ligula erat quis odio.  Nunc porta
  | vulputate tellus.  Nunc rutrum turpis sed pede.  Sed bibendum.  Aliquam posuere.
  | Nunc aliquet, augue nec adipiscing interdum, lacus tellus malesuada massa, quis
  | varius mi purus non odio.  Pellentesque condimentum, magna ut suscipit hendrerit,
  | ipsum augue ornare nulla, non luctus diam neque sit amet urna.  Curabitur vulputate
  | vestibulum lorem.  Fusce sagittis, libero non molestie mollis, magna orci ultrices
  | dolor, at vulputate neque nulla lacinia eros.  Sed id ligula quis est convallis
  | tempor.  Curabitur lacinia pulvinar nibh.  Nam a sapien.
  | </p>
  | </div>
  | </div>
  `----

In both emacs versions I have same results until I arribe here. I'm
not sure how to proceed to debug, any idea? Just ask me more information if needed.

PD: I attach my org-mode configuration since it's what is sugested,
but I don't know if it's relevant. I've only removed agenda related
variables.

Regards
