[O] 'wrong-type-argument stringp nil' when exporting (reftex/orgmode)

Subject: [O] 'wrong-type-argument stringp nil' when exporting (reftex/orgmode)
Date: Sat, 07 May 2011 11:46:53 +0200

Dear All,

I am using Org-mode version 7.5 (release_7.5.264.g94664) with GNU Emacs
23.2.1. When I do C-c C-e l (or any other export, not only latex), I get
the error (backtrace) below.

I use reftex with org-mode with the setup described in the FAQ, that
means in my .emacs is the following:

(require 'reftex) 
(defun org-mode-reftex-setup ()
  (load-library "reftex")
  (and (buffer-file-name)
       (file-exists-p (buffer-file-name))
       (reftex-parse-all))
  (reftex-set-cite-format
   "\\citep{%l}")
  (define-key org-mode-map (kbd "C-c )") 'reftex-citation))
(add-hook 'org-mode-hook 'org-mode-reftex-setup)
(setq reftex-default-bibliography '("/home/basil/docs/liball.bib"))

Any help is appreciated. Thank you!

Here comes the *Backtrace buffer*:
