Invalid files in ressource pack make Minecraft crash

Steps to reproduce:

• Create an empty text file (with Windows explorer or any other way) in ressource pack in minecraft/sounds/random

• rename to wood_click.ogg (with changing of file extension)

• press a wooden button in Minecraft with the ressource pack active

• Minecraft crashed (Windows says "doesn't react")

This is just one example I tried.

There is no real crash log, only the usual starting minecraft, loading world and saving world.
