I linted my yml on this website. Helped me find the error ASAP.

In my case it was due to having blanks at the end of the line after the } symbol.

I had this error once. It was because I didn't let a blank line at the end of my services.yaml file. Once I did so, no more errors !

There are some restrictions in yaml you have to be aware of. Symfony has a neat command line tool you can use to check if a yaml file is valid that will also try to point you to where the error lies. You can run it like this:

bin/console yaml:lint src/Gba/GbaBundle/Resources/config/services.yml

This will only do the lint on this one file you can also point it to a whole directory of files if you want.

My best guess is, that you have to put quotes around the services defined as arguments and in fact I prefer to quote every string value in yaml:

redirectionListener:
  class: 'Gba\GbaBundle\Listener\RedirectionListener'
  arguments: ['@service_container', '@session'] 
  tags:
    - { name: 'kernel.event_listener', event: 'kernel.request', method: 'onKernelRequest' }

Other things to look out for in yaml is correct indentation and mixing spaces & tabs.
