iOS 10 Glitch on Message.app

In this video, I crash the Messages app by an incoming iMessage on iOS 10.

With another device, I have send an iMessage which includes my code. After this the Messages app doesn’t work anymore.

In iOS 10 b1 & b2 I can’t fix this. But now I have created a “patch” (website with JavaScript function that open Message.app and it doesn’t crash (work 9/10).

Additional information:

Version: iOS 10 b2

Device: iPhone 6

Thanks to William for the help (english translation).
