The game crashes when opening the creative mode inventory.

What I expected to happen was...:
I would open my creative mode inventory.

What actually happened was...:
The game froze and switched to a screen with the minecraft dirt texture from the menus.

Steps to Reproduce:
1. Load a world in creative.
2. Press the E to open your inventory.
3. You should be at a dirt textured screen.

I have deleted and redownloaded the snapshot about 5 times, and the same thing happens. It's not a corrupted file...
