Invalid capture template with pull of Org 7.8.03?

[Damon Haley <news@vinylisland.org>]

Hi I was wondering if someone could point me in the right direction
because one of my Org capture templates, that I use to feed questions to
myself (for later use with org-drill) just broke with the most recent
bzr pull of emacs.

Now, when I try to use the capture template, I only get this header in
my target org file.

** Invalid capture template

I'm on the 24.0.92.1 version of emacs which ships with Org 7.8.03.

Here's the template, which I stole from:
http://orgmode.org/worg/org-contrib/org-drill.html

(add-to-list 'org-capture-templates
              '
              ("W"
               "Capture web snippet"
               entry
               (file+headline "~/git/org/learn-emacs.org" "Emacs mastery")
               ,(concat "* Fact: '%:description'        :"
                        (format "%s" org-drill-question-tag)
                        ":\n:PROPERTIES:\n:DATE_ADDED: %u\n:SOURCE_URL: 
%c\n:END:\n\n%i\n%?\n")
               :empty-lines 1
               :immediate-finish t))

Is there any obvious reason this template would break?

I know I could read the capture documentation further but I don't have a
few hours to spend on this right now (plus I'm extremely beginner with
lisp). But I'm pretty sure it just broke with a recent pull of emacs
without me changing any other settings.

Thanks for any help,

Damon

p.s. Here's the complete config that I used to try to debug the problem.

(global-set-key (kbd "C-c r") 'org-capture)
