Remember to cover the basics, that is, what you expected to happen 
and
what in fact did happen.  You don't know how to make a good 
report?  See

Your bug report will be posted to the Org mailing list.

Noticed that one cannot use a lambda function as a template 
generating function.
Doing so results in the error:

Wrong type argument: symbolp, (lambda...)

The cause is the fboundp check in org-capture-get-template.
Changing this to functionp allows a lambda to be specified and is 
consistent with what org-capture-set-target-location allows.

I'm not sure if there are any corner cases I'm unaware of, but it 
seems like a simple patch:

diff --git a/lisp/org-capture.el b/lisp/org-capture.el

 	  (setq txt (funcall (nth 1 txt)))
 	(setq txt (format "* Template function %s not found" (nth 1

      ((not txt) (setq txt ""))

Thanks,
