Were you running multiple guests at the time?  Was the guest where you 
did 'halt' running in full-screen mode?  If so, this sounds similar to:

Right now, my guess is that virt-manager is not handling guest-initiated 
shutdown cleanly, although we might reassign the problem to libvirt if 
it turns out to be a data race where libvirt isn't properly handling 
events during a guest-initiated shutdown, such that it leaks an 
unexpected error to the client instead.
