org-contacts-anniversaries 'Bad sexp' bug keeps haunting me

[Christoph LANGE]

Hi all,

for a while I had been able to run org-contacts-anniversaries with 
BIRTHDAY dates successfully, as explained at the bottom of 
https://julien.danjou.info/projects/emacs-packages#org-contacts.  This 
was on 64-bit Linux.  On 32-bit Windows I had the function disabled, as 
I have contacts both before 1970.  (See this thread: 
http://comments.gmane.org/gmane.emacs.orgmode/42139)

Now, for the first time, I'm running a 64-bit Emacs on Windows 
(http://emacsbinw64.sourceforge.net/).  I was confident that 
org-contacts-anniversaries would work for me, but it didn't.  Once more 
any invocation of an agenda involving org-contacts-anniversaries haunted 
me with the "Bad sexp" error message, pointing to the line in my 
contacts.org that contains "%%(org-contacts-anniversaries)".

I am running org-8.2.7c from ELPA, on Emacs 24.4.50.1.

I think I didn't make any of the mistakes documented previously:

* running a mixed Org installation (Org as bundled with Emacs, plus 
non-bundled packages; http://stackoverflow.com/a/15568713/2397768)

* using the wrong syntax for org-contacts-files 
(http://stackoverflow.com/a/14057170/2397768)

* using empty BIRTHDAY fields (http://stackoverflow.com/a/21968778/2397768)

* not having diary loaded 
(https://www.mail-archive.com/emacs-orgmode@gnu.org/msg48710.html – but 
isn't it actually loaded automatically by org-agenda.el when 
org-agenda-include-diary is set to t?)

FYI this is how I disabled org-contacts-anniversaries on non-64-bit 
systems:

; disable anniversaries on non-64-bit systems (as they don't handle 
dates before 1970)
(defadvice org-contacts-anniversaries (around 
disable-org-contacts-anniversaries-on-32-bit)
   "No anniversaries on 32-bit systems"
   (if (string-prefix-p "x86_64" system-configuration)
       (ad-do-it)))
(ad-activate 'org-contacts-anniversaries)

This code does not cause my problem.  I have tested it before, and 
without this code I'm still getting the "Bad sexp".

I'm giving up for now, reverting to manually maintained entries like 
this in my contacts.org:

%%(org-anniversary YYYY MM DD) Name (%d years)

Cheers, and thanks in advance for any helpful advice,

Christoph
