Reviewing block statistics causes client to crash

When reviewing block statistics, if you scroll down beyond a certain point, the client crashes. I was only able to recreate this effect on multi-player. I've attached the crash report. I've also recreated the crash on Windows 7 32bit with Java 7 as well. The message on the server reads:

lost connection: disconnect.genericReason

For some reason, the launcher thinks the game is modded, but it's not.
