I just updated a few hours ago with the git current version and I now get:

Debugger entered--Lisp error: (invalid-read-syntax "#")
  eval-buffer(#<buffer  *load*> nil "c:/Home/.org-timestamps/CQP-org.cache"
nil t)  ; Reading at buffer position 621
  load-with-code-conversion("c:/Home/.org-timestamps/CQP-org.cache"
"c:/Home/.org-timestamps/CQP-org.cache" nil nil)
  load("c:/Home/.org-timestamps/CQP-org.cache" nil nil t)
  load-file("c:/Home/.org-timestamps/CQP-org.cache")

Actually, the .cache file reads :

...
(puthash "c:/Home/Cours/CQP-ArTech/org/CQP-Artech-slides.org" '(:title
#("CQP-ArTech Slides" 0 17 (:parent (#("CQP-ArTech Slides" 0 17 (:parent
#3)))))) org-e-publish-cache)
...

I guess the #3 is the culprit. Any idea what went wrong?
