[libvirt] getting notified of events

I am trying to understand how to use the virEvent* API. I've built latest libvirt (with "Fix emission of domain events messages" commit) and run the domain-events example. events-c gives me mostly silence. nothing is printed when a domain changes state. events-python is more bizarre: it prints a line on every event - except for the first one, where "Updating Timeout 0 0 Poll sleep 1" is printed. Only when the second event occurs, does the callback for the first event gets executed. What am I missing? Could someone more familiar take a look? Regards, Dan.
