Same problem here with 13w39b :
Internal exception: java.io.IOException: Received string length longer than maximum allowed (74 > 64)
I opened to lan a world and connected perfectly to it 2 other accounts.
>>> It seems that place and use at least one Minecart with Command Block in the opened to lan world leads to this issue !
I've removed them and I have been allowed to connect again.
