laravel 4 returns error in file upload

Question

My problem is I am getting upload error when I try to upload a big image. (Greater than 2MB).

My upload size limit in php.ini is 40MB and I still get the following error:

 development.ERROR: exception 'Exception' with message Serialization of   Symfony\Component\HttpFoundation\File\UploadedFile' is not allowed in /var/www/laravel/vendor/laravel/framework/src/Illuminate/Session/Store.php:212
 Stack trace:

 #7 /var/www/laravel/public/index.php(61): Illuminate\Foundation\Application->run()
 #8 {main} [] []

Why do I get the error?

How are you trying to upload a file ? With native laravel upload functions of with bundle ? Permissions can be just one of the problems.
