ox-latex: Export ignores org-latex-classes from 4th level on

Hello,

the ox-latex file uses org-latex-classes to help, among other things,
with exporting headlines to the right commands, such as \section,
\subsection etc.

Unfortunately, not all headlines get exported correctly; the default
"article" class, as defined in ox-latex.el (see org-latex-classes
there), does for instance not use  "\paragraph" or "\subparagraph".

Here is an example file:


#+LATEX_CLASS: article

* First
** Second
*** Third
**** Fourth
***** Fifth
****** Sixth
******* Seventh
        This is the final text.


When I export, I get something like this:

[...]
\subsubsection{Third}
\label{sec:orgafa785d}
\begin{enumerate}
\item Fourth
[...]

However, it should use "\paragraph{Fourth}" instead, and not a list
with \item.

It seems there is something going on with the deep subtrees, starting
at line 1929 in ox-latex.el; (for the first 3 levels, line 1893 gets
called, too).

Can anyone see whats going on here? I'm currently on master. I tried
older versions, but this bug must have been there since 7.8 (I couldn't
compile many older versions any more or I couldn't export).

Thanks
Christian

PS: I couldn't find any news about the renaming (?) of org-export-
latex-classes to org-latex-classes. There is still quite a bit of
documentation out there, such as http://orgmode.org/tmp/worg/org-tutori
als/org-latex-export.html that refers to the former but doesn't work.
Is this intended?
