Export to Latex (org-latex-export-to-pdf) generates incorrect latex when
list items start with a left square bracket. This occurs because the
\item command interprets the left square bracket as the start of an
argument list. An example:

   An item list:
   - abc def
   - [def] ghi
   - [jkl m n o]
   - pqr

This produces the latex fragment:

   An item list:
   \begin{itemize}
   \item abc def
   \item [def] ghi
   \item [jkl m n o]
   \item pqr
   \end{itemize}

The pdf output renders the second and third items incorrectly. If there
is no right bracket to terminate the argument, then pdf generation may
fail with message:
  
   org-latex-compile: PDF file ./example.pdf wasn't produced: Runaway argument

I fixed these cases in my local environment using defadvise on org-latex-item
to wrap an initial left square bracket in braces. I used this form:

   (eval-after-load "ox-latex"
     '(progn
        (defadvice org-latex-item (after escape-initial-bracket activate)
          (setq ad-return-value
                (replace-regexp-in-string 
                    "\\\\item \\[" 
                    "\\\\item {[}" 
                    ad-return-value)))))

This changes the latex fragment for the above example to:

   An item list:
   \begin{itemize}
   \item abc def
   \item {[}def] ghi
   \item {[}jkl m n o]
   \item pqr
   \end{itemize}

This form renders PDF correctly. My knowledge of latex is very limited,
I don't know if this is a reasonable approach or not. There appears to
be one other function in the ox-latex.el generating the \item command:
(org-latex-headline). I did not try to reproduce this case.
