I noticed that the following sequence of events would crash libvirtd when using the qemu driver: (1) establish a connection that successfully registers for domain events (either of the event-test programs will do, though the python one is currently broken -- another patch on the way for that) (2) close this connection (3) open another connection (4) do something (like start a domain) that issues a domain event The problem is that qemudClose() isn't removing registered domain event callbacks when the connection closes. This patch does that, and fixes the crash.
