Re: Disable agenda file autoload?

[Carsten Dominik <carsten.dominik@gmail.com>]

You can try this:

Find the org.el file, and in it the definition of the function

(defun org-get-agenda-file-buffer

As the first ting after the documentation string, enter (debug), like  
this:

(defun org-get-agenda-file-buffer (file)
   "Get a buffer visiting FILE.  If the buffer needs to be created, add
it to the list of buffers which might be released later."
   (debug)
   (let ((buf (org-find-base-buffer-visiting file)))
     (if buf
	buf ; just return it
       ;; Make a new buffer and remember it
       (setq buf (find-file-noselect file))
       (if buf (push buf org-agenda-new-buffers))
       buf)))

Make sure there is no compiled version of org.el on the path.

Then run your first instance of Emacs.  During startup, I would expect  
that Org Emacs will stop with a backtrace buffer.  Show me that  
buffer, it will tell us which command loads agenda files....
