I'm not sure whether the server should ignore it or close the 
connection. But crashing is certainly not an alternative. Did you 
really mean crash, or just meant that the server drops the connection?

If it is really a crash, please entered this bug into the bug tracker 
system at http://bugs.jabber.org/

Hm, I see your problem. BTW, how is parsing in Flash? I remember 
someone told me Flash only finishes parsing after receiving a NULL 
byte, so this would be a problem, too, no?

I think this answers my question from above :)
