Wiki's TOC macro issue

Hi, I tried to use this TOC semantic: <<toc FAQ/>>. It's very great and cool macro which helps to split FAQ's entries on the small files. Suddenly, I found that it does not work for me.
It's bug? example:
http://bitbucket.org/tickling/test-repo/wiki/FAQ

Every time I get such an error when I try to browse FAQ entry
Wiki macro error: Either directory does not exist or no files found.

But, FAQ/* is there (in wiki's repo)! The syntax is valid. I even did tried push in the bb's help content there. No results. I found no issues about on the tracker. Please, enlighten me, what is wrong with the macro?

Thanks for your patience!
