Hi all,

Here is how to reproduce the bug:

1. create a file kk.el with the following content:

(setq org-modules nil)
(define-key mode-specific-map [?a] 'org-agenda)
(define-key mode-specific-map [?l] 'org-store-link)
(setq org-agenda-files '("~/kk.org"))
(setq org-export-with-LaTeX-fragments t
      org-highlight-latex-fragments-and-specials t)

2. create an empty file named "kk.org"

3. emacs -q -l kk.el

4. C-c a a
