I was playing around with the new texture pack system, and remember an old glitch where getting wool with a damage value of 16 makes it look like nether wart. I tested, and my game crashed. I feel this could be a serious bug if some worlds/servers have this block somewhere.

How to reproduce:
1) Go to single player or a snapshot server
2) Type the command: /give (yourname) 35
3) Crash

I am sure this works for 16, 17, and above 18 too.
