Error with Facebook 1.1.1

The facebook comments on my blog are back to the original wordpress standard after the update to 1.1.1.
Under settings in my admin page, I have an error that says:

Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘Facebook_Application_Settings::enqueue_scripts’ was given in /public_html/wp-includes/plugin.php on line 403
