symfony: Running `php app/console` strange database error

I have a Symfony2 application (2.6.x-dev, problem only occurs on 2.6.x) and I am running into some strange problems. If I delete the database that my application connects to and the run the following:

php app/console

It should display only a list of the commands I could run, but instead, it will throw the following error:

[PDOException]                                      
  SQLSTATE[HY000] [1049] Unknown database 'mango_db' 

Why is this happening? This way I can’t run the php app/console doctrine:database:create command, because it throws this exception.

If I switch to Symfony 2.5.x-dev, the problem goes away and I can run php app/console.

Here a detailed stacktrace when I access it through the browser (maybe some helpful information).
