I think, we find problem (thanks to Michail Pishchagin for help):
This looks like a bug in several jabber clients:
If user add server contact to roster (notafter recieving welcome 
message, for ex.), then remove it, clients send unregistration to 
server. If this user relogin, client creates new account, with new blank 
roster etc.

So, client program must check if servername in JID not equal of name of 
deleted service.
