This resolves a problem that occours in Symfony on the FileBag.php file, convertFileInformation() method. It receaves a empty array file and than returns NULL, if no files was selected on the upload. In this case "FileBag->set('image', NULL)" receives NULL, and that is what is dispatching a throw in Symfony.

I misunderstood the problem, and try attempt to do a pull request on symfony, but it was denied: https://github.com/symfony/symfony/pull/12486

I don't make unit tests, but this will no more break my code flow. I'm not sure if this is the real deal! If someone could look deeper into the problem, I appreciated!
