Hello,

I try to export a fontified LaTeX source code listing with HTML export.
It boils down to an error that is thrown upon execution of the following
function during HTML export:

(org-html-fontify-code "\\begin{tabular}{@{} l @{}}\n\\hline\nno leading space\\\\\n\\hline\n\\end{tabular}\n" "latex")

The debugging information is:
Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  expand-file-name(nil)
  reftex-TeX-master-file()
  reftex-reset-scanning-information()
  reftex-reset-mode()
  my-reftex-mode-hook()
  run-hooks(reftex-mode-hook)
  reftex-mode(t)
  turn-on-reftex()
  run-hooks(change-major-mode-after-body-hook text-mode-hook TeX-mode-hook LaTeX-mode-hook)
  apply(run-hooks (change-major-mode-after-body-hook text-mode-hook TeX-mode-hook LaTeX-mode-hook))
  TeX-run-mode-hooks(text-mode-hook TeX-mode-hook LaTeX-mode-hook)
  TeX-latex-mode()
  apply(TeX-latex-mode nil)
  latex-mode()
  org-html-fontify-code("\\begin{tabular}{@{} l @{}}\n\\hline\nno leading space\\\\\n\\hline\n\\end{tabular}\n" "latex")
  eval((org-html-fontify-code "\\begin{tabular}{@{} l @{}}\n\\hline\nno leading space\\\\\n\\hline\n\\end{tabular}\n" "latex") nil)
  eval-last-sexp-1(nil)
  eval-last-sexp(nil)
  call-interactively(eval-last-sexp nil nil)
  command-execute(eval-last-sexp)

All the best,
Dominik
