[MC-63507] Clicking 'Snooper Settings' crashes Minecraft

Clicking 'Snooper Settings' crashes the Minecraft window. I know not many people bother with Snooper Settings but I felt like it needed to be addressed

What I expected to happen was...:
I expected to be shown the Snooper Settings, per usual

What actually happened was...:
Upon clicking the Snooper Settings button, the game showed the plain dirt background for about a second, then crashed and slapped me across the face with an error report

Steps to Reproduce:
1. Load Minecraft 14w30c
2. Head into Options
3. Click 'Snooper Settings'
4. Wait for your game to crash
