Server Kicks Client: Forcibly Removed

On any of the 1.7.* versions (since the new net code for servers was implemented) I seem to keep getting the following error:

'Internal Exception: java.io.IOException: An existing connection was forcibly closed by the remote host'

This is causing problems for my collegues as well when we try to record Youtube videos on the new versions. We have had to resort to sticking with the 1.6.4 version of Minecraft at the moment until this bug is fixed.
