[BUG][PATCH] Commit '3142297d69f6063221215757a3ba9c74adcf3e43' breaks some my files

[Vladimir Lomov <lomov.vl@gmail.com>]

Hello,
as title states, commit '3142297d69f6063221215757a3ba9c74adcf3e43'
breaks one of my Org document (I have many but faced with a bug only
with particular one). In that file tables contain data (three columns,
one header) which are transformed and tangle to files (xml, txt). Before
the commit '3142297d69f6063221215757a3ba9c74adcf3e43' all works fine,
begining with it I can't tangle files with error message
BEGIN_EXAMPLE
  mapc: Wrong type argument: consp, nil
END_EXAMPLE

By means of trial-and-error I made small patch which fixes the problem
for me. As I'm know very few in Emacs Lisp I'm not sure if my fix is
correct, so I just added two lines without "proper" reindenting of whole
block.

BEGIN_EXAMPLE

     ;; clear out col-names and row-names for replaced variables
+    (when (and (consp :colname-names) (consp :rowname-names))
     (mapc
      (lambda (name)

        (let ((key (intern (concat ":" (symbol-name hd))))
END_EXAMPLE


P.S. I was lazy to prepare MWE. The mentioned document is available at
