Realized after I opened that I'm way behind on version, but it would still be nice to know what causes this so I can avoid it in the future. gonna kill the crafter blocks with MCEdit to recover my server for now

Issue description:

Was doing some autocrafting, server crashed, now crashes on load.

What happens:

Null dereference...

What you expected to happen:

The server not to crash...

Steps to reproduce:

We were autocrafting compressed cobble, redstone blocks, and added glowstone dust -> glowstone a few seconds before the crash occured.
...

Version (Make sure you are on the latest version before reporting):
