I think I have the same problem. Also some "TODO" keywords are now highlighted in some headings but it could be related.

In the "*messages*" buffer I have:
font-lock-fontify-keywords-region: Wrong type argument: listp, org-level-1Error during redisplay: (jit-lock-function 240) signaled (wrong-type-argument listp org-level-1)
Error during redisplay: (jit-lock-function 1906) signaled (wrong-type-argument listp org-level-1)
Error during redisplay: (jit-lock-function 8102) signaled (wrong-type-argument listp org-level-1)
Error during redisplay: (jit-lock-function 9663) signaled (wrong-type-argument listp org-level-1)

I just updated org-mode from Elpa and since then links in headings are
not anymore interpreted as links.  Example:

* [[http://www.google.com][Google]]

I’d expect to see

* Google

with “Google” being clickable but instead I see the complete code for
the link.  Links in normal text work as usual.

Tested with Emacs -Q on a recent development version of Emacs.
