When hitting my Play/Pause button on both my Mouse and Keyboard crashed Minecraft. It has crashed at the menu and in game.
Steps to reproduce:
1. At Menu (or in game) press Play/Pause button.
2. Game crashes...
This never happened until I upgraded to the snapshot.
EDIT: Tested hitting the "Next" button and that will also reproduce this. It seems any audio related buttons will crash.
So no idea what happened but it seems it's all good now? I was about to reproduce to get a log of the console but nothing happens?
