Toc on dir does not work

Hi! I tried many times wiki's TOC on directory feature, but, without any success Every time I got an error
Wiki macro error: Either directory does not exist or no files found.

I use an empty sandbox repo and real one, but, the results are the same. What are files there?

{{{
$ tree
.

hg clone http://bitbucket.org/tickling/test-repo/wiki/

{{{
$ hg log

test toc on dir

Well, I tried {{

{<<toc FAQ/>>}

}} and {{

{<<to FAQ/ 3>>}

}} as described here http://bitbucket.org/help/FAQ/wiki#how-can-i-add-a-table-of-content

Thanks, if you have read until here
