When I try to put schema.org property image at an image field I get a White screen of death.
PHP error message Fatal error: Call to undefined function _field_permissions_field_settings_form_submit() in /var/www/drupal/includes/form.inc on line 1414

Disabling Field Permissions module (http://drupal.org/project/field_permissions), does not give a WSOD, but still does not save the new mapping as referrred at http://drupal.org/node/1297168.
