Alright so heres my problem minecraft 1.4.2 has been working beautifully up til now I've been able to login, play single player, multiplayer, everything. But recently I was playing on a 1.4 server and I typed in the command /spawn. I had been playing on that server in 1.4 for a day and a half and all the commands were working but for some reason when I typed in /spawn minecraft decided to crash. Now whenever I log into any server it connects and logs in but stays on the background that the "logging in..." has behind it for about 5 seconds then crashes.

Here is the bug report:

Minecraft has crashed!
