[O] Bug: org-wikinodes: Failed to add wikinodes to `org-font-lock-extra-keywords'. [8.2.10 (8.2.10-30-gca21b7-elpa @ /home/scott/.emacs.d/elpa/org-20150202/)]

[Scott Campbell]

Hello.

I started testing org-wikinodes, and although the functionality seems to
work (C-c C-o links from CamelCase words to headlines, with new
headlines created as necessary), I can't get the face to change to match
plain links. When I load an org file with CamelCase words/headlines, I
get an error:

"Failed to add wikinodes to `org-font-lock-extra-keywords'"

I've done what I can to isolate what's going on, trying various
combinations of running without my init file, without site-lisp, and so
on. The only way I can get it to work is if I explicitly exclude
everything except the org-wikinodes library. So, if I start with:

$emacs -Q -l .emacs.d/elpa/org-plus-contrib-201401026/org-wikinodes.el ORGFILE

then it works. But the org version is 7.9.3f, which is presumably what
ships with ubuntu 14.10. I've tried starting with an empty .emacs file,
so that it only pulls in the site-lisp, and then it fails again. I
couldn't see a difference between org-set-font-lock-defaults in org.el
version 8.2.10 and 7.9.3f, so I don't know why or what might be going on
here. Other plain links work fine (ie: http://google.com, bib:testentry,
etc). Enclosing the CamelCase in brackets (ie: [[TestLink]]) is fine. 

I've included my org setup below, excepting org-agenda-files, which I
removed for privacy reasons.

If anyone has as suggestions for getting to the bottom of this, I'd be
grateful. I used to use emacs-wiki.el, way back over a decade ago and
wanted to get back into something similar. The org-wikinodes package
seemed to fit the bill, but this is a bit of a stumbling block.

Are there packages known to cause problems with faces/font-locking in
org-wikinodes? Is there another way to get wikinodes added to
org-set-font-lock-defaults? Is there anything else I could do or provide
to make debugging easier?

Thanks!
Scott
