Yes, you are right.  So Richard, this should be equivalent to what
you've user previously:

(defun skim-make-url ()
  (concat
   (TeX-current-line)
   " \""
   (expand-file-name (TeX-active-master (TeX-output-extension) t)
                     (file-name-directory (TeX-master-file)))
   "\" \"" (buffer-file-name) "\""))

Please report back if it works so that we can close the bug accordingly.

Bye,
