angularjs + yeoman + ng-switch + build:minify -> assertion

I am using an ng-switch in angularjs to have dynamic content in my page, dependent on the url. And I am managing my project with yeoman. Here is the code of the dynamic content generation:

html:

<div class="div-content bgcontent" id="content">
  <span ng-switch on="renderPath[0]">
    <div ng-switch-when="home" ng-include="'partials/home.html'"></div>
    <div ng-switch-when="gallery" ng-include="'partials/gallery.html'"></div>
  </span>
</div>

controller:

$scope.renderPath = $location.path().split('/');
// remove first entry because it's empty string
$scope.renderPath.shift();

This works perfectly well when running the stuff with 'yeoman server'. But if I build with 'yeoman build:minify', it doesn't work anymore afterwards. It hits an assertion:

Does someone know how to fix this? Or where I need to look to debug it?
