Bells crash the game

I wouldnt call this a major bug but i thought i would send it in anyway.

So after messing around with bells in a creative world i have discovered that if you try and move a bell with a sticky piston the game freezes and crashes 100% of the time, i know players most likely wont attempt this but i did for some reason =D

 

EDIT, 

Looks like the same thing happens when you try to move a sticky piston with a sticky piston
