Using Wooden Tools As Fuel Crashes Some Servers

What I expected to happen was...:
Burning The Tools To Use As Fuel For Smelting Ores And Other Resources

What actually happened was...:
Using Wooden Tools As Fuel Killed The Chunk And Would Crash The Server Anytime Someone Entered That Chunk.

Steps to Reproduce:
1. Put Any Wooden Tool In The Furnace
2. Put A Cookable or Smeltable resource into the furnace
3. The Chunk dies and when someone enters the chunk the server crashes
