Well, when I reported the problem, it was first time it appeared, so I didn't
consider it big deal, but yesterday we got it again, on different server
(but the backtrace is completely the same) But it was the same person as
before (and quite a new user to our KVM guests), so I suspect it can be
something specific to his client or setup. I'll try to look at it deeper
and let You know if I figure something out...

cheers
