Error with Theme Options Page

May be a simple fix, but posting anyway as it may be useful feedback.

Just got the latest git pull (20090611)

On home page going thru the menus to 'theme options' I get this:

 So here's the error:
The page you requested, admin/theme_details, could not be found.

File: system/core/Kohana.php, line: 841
And here's how we got there:

    * modules/gallery/controllers/admin.php [47]:

      Kohana::show_404(  )

    *

      Admin_Controller->__call( theme_details )

    * system/core/Kohana.php [291]:

      ReflectionMethod->invokeArgs( Admin_Controller Object
      (
          [theme:private] => 
          [uri] => URI Object
              (
              )

          [input] => Input Object
              (
                  [use_xss_clean:protected] => 1
                  [magic_quotes_gpc:protected] => 1
                  [ip_address] => 
              )

      )
      , Array
      (
          [0] => theme_details
          [1] => Array
              (
              )

      )
       )

    *

      Kohana::instance(  )

    * system/core/Event.php [209]:

      call_user_func( Array
      (
          [0] => Kohana
          [1] => instance
      )
       )

    * system/core/Bootstrap.php [55]:

      Event::run( system.execute )

    * index.php [81]:

      require( system/core/Bootstrap.php )

Hope this makes sense to someone...

Thanks in advance
