[O] Problem with Including subsection by CUSTOM_ID

[Ilya Filippov]

I try to include subsection from one org-file to another 
(http://orgmode.org/manual/Include-files.html) with using CUSTOM_ID.

In first-file.org:

** Subsection name
:PROPERTIES:
:CUSTOM_ID: subsec_to_include
:END:

bla-bla


In second-file.org I use construction:

* I want include here
#+INCLUDE: "./first-file.org::#funcNT10"


And when I export second file to PDF, org-mode gives an error message: 
"Cannot include file /org/first-file.org::#funcNT10"

PS: internal link  "./first-file.org::#funcNT10" in org-file works.
      #+INCLUDE: "./first-file.org" - also works.


May be I need add something to .emacs?
