This should be fixed on the Org side as of 44c8cd7 (2015-08-10):

    org-map-entries: Fix org-agenda-prepare-buffers call
    
    * lisp/org.el (org-map-entries): Check that buffer-file-name is non-nil
      before passing to org-agenda-prepare-buffers.
    
    Like 11e8749, this surfaced as an error when 05efa7a ("Backport commit
    3a5f751 from Emacs master branch", 2015-08-08) replaced a
    '(while (setq VAR (pop LIST)) BODY)' with '(dolist (VAR LIST) BODY)',
    resulting in the body being executed when '(nil)' was passed to
    org-agenda-prepare-buffers.
