Bug: reftex breaking after org-mode export [8.2.10 (8.2.10-35-g19a7d6-elpa @ /Users/adamjackson/.emacs.d/elpa/org-20150323/)]

Hi,

I've been struggling with Reftex in org-mode. Initially things are fine,
then after exporting the document to LaTeX and continuing to work with
org-mode, using most of the reftex features (e.g. reftex-toc or trying to
insert a reference) produces a "Wrong type argument: stringp, nil" error
message.

The code in my init file to set up reftex:

    ;; Reftex
    (require 'reftex)
    (defun org-mode-reftex-setup ()
      (load-library "reftex")
      (and (buffer-file-name) (file-exists-p (buffer-file-name))
         ;enable auto-revert-mode to update reftex when bibtex file changes on disk
         (global-auto-revert-mode t)
         (reftex-parse-all)
          (define-key org-mode-map (kbd "C-c [") 'reftex-citation)
         ;add a custom reftex cite format to insert links
         ;; (reftex-set-cite-format "** [[papers:%l][%l]]: %t \n")
         )
    ) 

    (add-hook 'org-mode-hook 'org-mode-reftex-setup) 

At the moment I still enter reftex-mode on demand with "M-x reftex-mode".
Here is the backtrace for the error:

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
