Reproducable Disconnect

I think I've figured out a way to reproduce this disconnect. I'm trying to sell items, so I'm doing the usual WTS > items thing in general chat, but for the past 3 times I've tried to repeat what I've typed using the arrow keys to get to previous messages, it forces me to disconnect when I get to that message.

Here's a cleaned up version:

Bug: Disconnecting when repeating previous message containing max number of linkable items.

Steps to repro: Initial posting of message is fine, but hitting enter and then the up arrow key causes a disconnect.
