As discussed in http://www.igniterealtime.org/forum/thread.jspa?threadID=24992 it may also be a debug window issue - it seems that < and > are not properly escaped when using the ad-hoc message window.
So one can send valid XML but invalid XMPP data.
Receiving invalid data should anyhow not disconnect the receiving client.
