Ctrl-Backspace CTD

I was playing the snapshot, and renaming my pick in an anvil, and used Ctrl+Backspace to clear the words, and I accidentally did it with no text in an anvil. It crashed the game. I tried it again, with the express intent of replicating it, and it happened. To replicate EXACTLY what I did, place two pickaxes in an anvil (to combine enchants), and clear the name area using Ctrl+Backspace. When the area is empty, press Ctrl+Backspace again. You should CTD.
