Ooops, I spotted a minor in my patch.

Subject: [PATCH] ox-latex: convert verbatim text in headings to tt

* lisp/ox-latex.el (org-latex-format-headline-default-function): Convert
any instances of \verb text with \texttt.  This is required to work
around LaTeX peculiarities that would otherwise cause compilation to
fail (see the code comment for more information).
