Crash when resource pack doesn't have animation metadata

What I expected to happen was...:
Minecraft would apply the resource pack

What actually happened was...:
When selecting the resource pack it gives errors (doesn't crash yet) like:

Client> 2013-06-14 16:05:27 [CLIENT] [SEVERE] Unable to parse animation metadata from minecraft:textures/items/compass.png

When then selecting another resource pack it completely crashes (crash report attached).

Steps to Reproduce:
1. Go to Options from the menu
2. Go to Resource Packs
3. Select a Resource Pack without animation metadata (you will get errors)
4. Select any other Resource Pack
5. Minecraft crashes
