Hmm, how many entries are in your host list when this works? I can't reproduce locally.
Hi Cole, I tried about 10-20 times,click "Connect to remote host" very quickly.
Yeah I tried that, I still can't reproduce. When you click 'connect to remote host', how many hostnames are added to the hostname: dropdown? I wonder if this issue is dependent on having many libvirt hosts on your network.

Okay, I can reproduce on my LAN but I have to enable/disable many times. We should just set up avahi polling once, and always have it running in the background, rather than try and tear it down when the check button is clicked. But this is urgent for RHEL so moving to upstream tracker.
Upstream now
