defaults_ie.css call seems to be incorrect

I think line 7 of template.php (it is calling /css/defaults_ie.css in header no path to theme)

drupal_add_css(drupal_get_path('theme', 'WORKING_COPY') . '/css/defaults_ie.css', array('weight' => CSS_THEME, 'browsers' => array('IE' => 'lt IE 9', '!IE' => FALSE), 'preprocess' => FALSE));

should be

drupal_add_css(drupal_get_path('theme', 'layoutstudio') . '/css/defaults_ie.css', array('weight' => CSS_THEME, 'browsers' => array('IE' => 'lt IE 9', '!IE' => FALSE), 'preprocess' => FALSE));
