[O] Org-sync with redmine

[Tim]

    I would really like to use org-sync to keep my org file and redmine in sync.
Unfortunately , this is completly unusable for me at the moment.  I followed 
the instructions , but it just clears the buffer of any text and doesnt do 
anything else.  There are messages in the *Messages* buffer saying that it is 
pulling tickets, but they are not added to the buffer, and i get the following 
error:

Debugger entered--Lisp error: (wrong-type-argument arrayp nil)
  substring(nil 0 -1)
  (replace-regexp-in-string "^" ": " (substring (org-element-property :value 
fixed-width) 0 -1))
  org-element-fixed-width-interpreter((fixed-width (:value nil)) nil)
  funcall(org-element-fixed-width-interpreter (fixed-width (:value nil)) nil)
  (cond ((not type) (mapconcat ... data "")) ((eq type ...) (mapconcat ... ... 
""))
 ((stringp data) data) ((not ...) (funcall ... data nil)) (t (let* ... ...)))
  (let* ((type ...) (results ...)) (if (memq type ...) results (let ... ...)))
  org-element-interpret-data((fixed-width (:value nil)) (section nil 
(property-drawer (:properties ...))
 (fixed-width (:value nil))))
 ...

Any idea where i should look for what may be causing the error ?
