Loading Scenes from Asset Bundle

I am currently looking into AssetBundles for a current project, where I need to be able to load new Scenes from external sources, without rebuilding the application. AssetBundles seemed ideal for this, but I encountered a little roadblock when I try to load Scenes form a bundle.

Loading the bundle itself is not a problem, and also getting the scene paths ist quite straight forward, but these paths are unusable.

This is what I currently do in order to load a scene from a bundle, which looks extremely stupid to me...

Code (CSharp):

1. private void LoadBundle() {
2.  
3.         AssetBundle bundle = AssetBundle.CreateFromFile("AssetBundles/testbundle");
4.        
5.         Application.LoadLevel(ToScene(bundle.GetAllScenePaths()[0]));
6.     }
7.  
8.     private string ToScene(string path) {
9.  
10.         string[] parts = path.Split('/');
11.  
12.         string scene = parts[parts.Length - 1];
13.  
14.         return scene.Remove(scene.Length - 6);
15.     }

Is there a better way to get a usable string to load a Scene than this? Or is this an oversight on Unity's part?
