ClassNotFoundException: Attempted to load class "FlattenException" from namespace

I am developing an application using Symfony 2.4 and doctrine mongodb bundle. I have faced an annoying error saying:

ClassNotFoundException: Attempted to load class "FlattenException" from namespace "Symfony\Component\Debug\Exception" in /opt/apps/aff/vendor/doctrine/mongodb-odm/lib/Doctrine/ODM/MongoDB/Cursor.php line 455. Do you need to "use" it from another namespace? Perhaps you need to add a use statement for one of the following: Symfony\Component\HttpKernel\Exception\FlattenException, Symfony\Component\Debug\Exception\FlattenException.

This error occurs especially when visiting sonata admin bundle's list methods. I have faced with this error also when playing repository classess.

The exact code is running perfectly on the remote server. But on the local machine this error is occuring. I do not know why. I have run the following code on terminal to see version numbers or git commit ref codes.

$ php composer.phar show -i

The result is axactly same on both computers. The following is my composer.json

I am really confused and I do not know how to procceed. What is the meaning of this annoying exception?
