 xdg-user-dirs-gtk is a companion to xdg-user-dirs that integrates it into
the Gnome desktop and Gtk+ applications.

It gets run during login and does two things:
* Tracks changes of locale and prompts the user so the directories
  can be changed.
* Creates a default gtk bookmarks file if there is none, based
  on a set of xdg user dirs.
