Hi,
  since some days ago I get an export error after C-a a, batch export, C-e on .org files, … Backtrace at the end.

  Even (avl-tree--root org-element--cache) or (avl-tree--root nil) produce the same error.

  This is not a bug in org, but in Emacs 23.4.1. avl-tree.el says:

(defmacro avl-tree--root (tree)
  ;; Return the root node for an avl-tree.  INTERNAL USE ONLY.
  `(avl-tree--node-left (avl-tree--dummyroot tree)))

  And it should have a comma before the word „tree“ in the body. Like this (org-mode works with this):

(defmacro avl-tree--root (tree)
  ;; Return the root node for an avl-tree.  INTERNAL USE ONLY.
  `(avl-tree--node-left (avl-tree--dummyroot ,tree)))

  This was fixed in emacs from Bazaar (in rev. 104392, Fri 2011-05-27 20:03:26 -0300).

  But at the moment org-mode does not work in Emacs 23.4.1, so I think it should have a work-around.
  The fix can be: „if Emacs version is lower than […] then define the macro again with the correct code“. Like:

(if (version< emacs-version "24")
  (defmacro avl-tree--root (tree)
  ;; Backport fix for older versions due to missing comma in ,tree
  `(avl-tree--node-left (avl-tree--dummyroot ,tree)))
)


  Thanks,

Daniel
