I've hit the bug myself, but never filed a BZ - it's quite annoying that
the shutdown button in virt-manager fails to work if you have the guest
agent wired up in the host XML, but not installed and running in the
guest, at which point you can no longer shut down the guest using
virt-manager.  Yes, I think this is safe to push for 1.0.3.
