EDIT: This has been fixed in snapshot 14w08a.

When trying to display a scoreboard objective using a tellraw command (/tellraw @a {score:{name:"playername",objective:"test"}}), the game crashes. I have uploaded my crash report.

Steps to reproduce:
1. Create a scoreboard objective.
2. Run the command /tellraw @a {score:{name:"playername",objective:"objectivename"}}
3. The game will crash:
