[O] org-info.js not displaying document?

[Greg Minshall]

hi.  i'm trying to export a file using org-info.js, but i'm not getting
anything (other than the footer with my name, creation date, and an
offer to validate the file) when i open the resulting html file
(everything is *in* the html file, it just isn't showing up).  i'm using
a very simple
----
#+INFOJS_OPT: view:showall toc:2
----
a simple test case is below

i know nothing about javascript.  but Firefox (42.0) on my macosx
(10.10.5) has Tools:Web Developer:Console, which says:
----
TypeError: k.T is undefined
----
on org-info 81:85

possibly the offending section of code is:
----
k.T=k.B.getElementsByTagName("h1")[0];
----

i'm running
----
Org-mode version 8.3.2 (release_8.3.2-338-g522ec9 @
/Users/minshall/usr/share/emacs/site-lisp/org/)
----
on
----
GNU Emacs 24.5.2 (x86_64-apple-darwin14.4.0, GTK+ Version 2.18.9) of 2015-11-22 
on greg-minshalls-mbp-2.local
----

any thoughts?  if i didn't see the error message, i'd be sure i was
doing something wrong (but, possibly i still am).

cheers, Greg Minshall

ps -- here is a trivial file that fails for me:
----
* testing
#+INFOJS_OPT: view:showall toc:2

this is a test

** here is something
** here is something else

with some text after it
