ReflectionException #-1 Class does not exist after update to Nette 2.4

Hi,
in our project config, we have a service defined like this:

    ceneoService:
        class: Project\Control\Tracker\Component\Ceneo\Service\CeneoService
        arguments:
            - ...
            - @session::getSection('ceneoService')
            - @controlSettingsLoader::load(Project\Control\Tracker\Component\Ceneo\Conversion\CeneoConversionControl)::get('langs')

where CeneoService is service with constructor like this:

    /**
     * @param Lang $lang
     * @param SessionSection $session
     * @param array $allowedLangs
     */
    public function __construct(Lang $lang, SessionSection $session, array $allowedLangs)
    {

(Lang is autowired).
@controlSettingsLoader is name of a service, that loads a new Settings object for given control (Settings class then have method get to access specific setting section).

With Nette 2.3 everything worked fine, but after update to Nette 2.4 we are getting “ReflectionException #-1 Class does not exist” error caused by Container builder trying to call autowireArguments with empty string: http://pasteboard.co/aAEOoGsoA.png

If I rewrite definitions of the service to separate services…

    ceneoService:
        class: Project\Control\Tracker\Component\Ceneo\Service\CeneoService
        arguments:
            - ...
            - @session::getSection('ceneoService')
            - @ceneoSettings::get('langs')

    ceneoSettings:
        class: Inspire\NW7\Application\Settings
        autowired: false
        create: @controlSettingsLoader::load(Project\Control\Tracker\Component\Ceneo\Conversion\CeneoConversionControl)

…it works, but it is not so handy and comfortable as it was. Is there any way, how to make the first, “short” definition to work and compile? I didn't find in changelog that format or way how to write service definitions has been changes, so maybe it is a bug?

Thanks!
