Has anyone ideas? Thx

Probably looking into your examples the problem is in your behat.yml configuration file. default is a name of your profile and extensions key is a child of that profile. So each line below default profile should has addition 4 spaces.

default:
    extensions:
        Behat\Symfony2Extension: ~
        Behat\MinkExtension:
        base_url: http://integration.fvs.dev.intern.etecture.de/private-clients
        browser_name: 'firefox'
        selenium2:
            wd_host: http://hub.selenium.intern.etecture.de:4444/wd/hub
            capabilities: { "browser": "firefox", "version": "14"}
        goutte: ~
        sessions:
            goutte:
                goutte: ~
            selenium2:
                selenium2: ~
            symfony2:
                symfony2: ~
    suites:
        backend:
            type: symfony_bundle
            mink_session: selenium2
            contexts:
                - app\features\bootstrap\FeatureContext:
                    screen_shot_path: app/screenshot
