Jasmine: Null or Boolen injected into $controller freezes test

My karma/jasmine testing freezes when I pass a boolen or a null to the $controller parameter injection. If I comment that line or code at least I get the expected error, but if I include it the test doesn't do anything until it disconnects itself. Any idea/solution please? Here's the part of the code (the activeTab value is the problematic one):

beforeEach(inject(
    function (_$rootScope_, _$location_, _App_, _$q_, _LocationParams_, _filtersFn_, _progressBar_, _$httpBackend_, $controller) {

      $rootScope = _$rootScope_;
      $scope = $parentScope = $rootScope.$new();
      $scope.$parent = $parentScope;
      $scope.$parent.$parent = $parentScope;
      $location = _$location_;
      appFactory = _App_;
      $q = _$q_;
      LocationParams = _LocationParams_;
      filtersFn = _filtersFn_;
      progressBar = _progressBar_;
      $httpBackend = _$httpBackend_;

      ctrl = $controller('AppIndexCtrl', { 
        $scope: $scope,
        $location: $location,
        App: appFactory,
        data: _data,
        LocationParams: LocationParams,
        activeTab: null,
        filtersFn: filtersFn,
        progressBar: progressBar
      });
  }));
