Unity 5.0.1f1 web player crashes/locks OSX

I'm stuck and I need some help.

Firefox and Safari both load the web player, show my title screen, and fully crash both Mavericks and Yosemite to the point of requiring a hard reset.

It occurs after the title screen's Start button is clicked and the game tries to transition to the next scene. My guess is that it's happening in LevelController.cs when trying to load the next scene, though I haven't been able to discern why.

Specifically, line 19 in this chunk of code that handles a fade in/fade out between scenes:

Code (CSharp):

1.  
2. void OnGUI(){
3.     if(isTransitioning){
4.         // next alpha value
5.         alpha += fadeDir * fadeSpeed * Time.deltaTime;
6.         alpha = Mathf.Clamp01(alpha);
7.  
8.         // Can't change GUI.color values directly, so create temp color
9.         Color color = GUI.color;
10.         color.a = alpha;
11.         GUI.color = color;
12.  
13.         GUI.depth = drawDepth;
14.         GUI.DrawTexture(new Rect(0, 0, Screen.width, Screen.height), fadeOutTexture);
15.  
16.         // When increasing alpha, and at a reasonable cap, load the next scene
17.         //   defined in the inspector. We only fade out when changing scenes.
18.         if (fadeDir > 0 && alpha >= 0.99f) {
19.             Application.LoadLevel(nextSceneName);
20.         } else if (alpha < 0.01f){
21.             isTransitioning = false;
22.         }
23.     }
24. }
25.  
26.  

There's something I'm missing here. Where do I start?

Web player here: (you've been warned!)

Full source is here:

Built with Unity 5.0.1f1

 

Is it okay to bump this? It was posted pretty late, and I'd still like to get our Ludum Dare entry running in the webplayer.

 

This other Ludum Dare entry appears to suffer from the same issue. Anyone wanna verify that this is reproducible?

Hmm. That is a strange one. Just rebooted my machine. :-(

 

When I use Chrome, I get:

Receiving unhandled NULL exception
Exit with error code: 2

========== END OF STACKTRACE ===========

I assume FF and Safari crash in the same way, but don't handle the exception as well. I can't explain what is happening, :-(.

 

Here you are: 692061

It's loading fine for me too but locks the system after clicking Start.

Edit: Nice goggles.

 

We suddenly started having this problem when upgrading a project to 5.3.1. Was there any resolution?
