[O] Bug: org-datetree.el references undefined function org-find-property [8.2.10 (release_8.2.10 @ /Users/damien/.emacs.d/elpa/org-plus-contrib-20160314/)]

[Damien Pollet]

Hi. When invoking org-capture to add an entry to my journal, Emacs
sometimes complains that "symbols's function definition is void:
org-find-property". Very much like in this report:

https://lists.gnu.org/archive/html/emacs-orgmode/2016-02/msg00267.html

M-x describe-function does not find that symbol. I found an occurrence
of it in org-datetree.el, and a colleague recommended to (require
'org-datetree) but that didn't have any effect.

I usually open an org-mode file and retry the org-capture, and sometimes
that makes the problem go away, but not today, it seems. This is with
Spacemacs master, keeping all packages pretty up-to-date with Melpa etc.

Thanks in advance
