4.1 Web player problem with 4.0.1 project

Unity3D 4.0.1 project that make use of Mecanim blend trees can’t run in version 4.1 unity web player

my project runs fine in the editor and in desktop build, but a web player build always crash when a model transit to an animation blend tree. had to replace all blend tree with a single animation for it to run without crash.

Hello,

Could you please file a bug report to us? include the repro project and the WebPlayer build and I will have a look for you.

Let me know the 6-digit case id.

Thanks,
Chris

I fought all morning isolating this exact same problem.
Upgrading from v4.01 to 4.1.2f just fixed this for me.
