sign kicks you in 1.9 snapshot!

when you place a sign on a server (not tried on single player) it will kick u and not let you back on

EDIT: when i go to sign into any servers i get "Internal Exception:io.netty.handler.codec.decoderexception:java.lang.IndexOutOfBoundsException:readerIndex(9)+length(1) exceeds writerIndex(9): UnpooledHeapByteBuf(ridx: 9, widx: 9, cap:9)
