To trigger the bug:
1. Go into creative
2. Press "e" to open your inventory.
3. Click the compass
4. Then type "craft"
5. Nothing happens, crafting table doesn't pop up.
6. if you type "crafti" or "craftin" or crafting" it will come up, but only typing craft nothing happens.

This works for multiplayer and singleplayer. In 1.7 when you type craft it works, its just a 1.8 thing.

Thanks
