gtk_rc_get_module_dir() returns wrong path

["Sergey I. Kuzminov" <ksi sparc spb su>]

Hi all,

gtk_rc_get_module_dir() returns the directory which GTK+ looks for theme engines
in (see docs).
But it looks like this directory doesn't exist in built space.

What's wrong ?
Where  gtk_rc_find_module_in_path() will search theme engine modules ?

Thanks for any help,
Sergey
