Broken with Laravel 4.1?

I'm trying to install this via your instructions. However when I attempt to publish the config file I get this error:

PHP Fatal error: Class 'Frozennode\XssInput\XssInputServiceProvider' not found in /var/www/vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php on line 123
{"error":{"type":"Symfony\Component\Debug\Exception\FatalErrorException","message":"Class 'Frozennode\XssInput\XssInputServiceProvider' not found","file":"/var/www/vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php","line":123}}{"error":{"type":"Symfony\Component\Debug\Exception\FatalErrorException","message":"Class 'Frozennode\XssInput\XssInputServiceProvider' not found","file":"/var/www/vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php","line":123}}

Can you check your /vendor/composer/autoload_namespaces.php file to verify that the namespace is being autoloaded?

Seems to be there:

'Frozennode\XssInput' => array($vendorDir . '/frozennode/xssinput/src'),

It seems to be working now. I deleted my vendor/ dumped my autoload, and cleared my artisan cache

hmmm...on a updated L4.1 install this isn't working again, I've tried my previous fix, but it seems to be broken again with the same error.
