Xenial: Error polling connection 'qemu+ssh://user@host/system': 'NoneType' object has no attribute 'getInfo'

[Mike Pontillo]

Whenever I suspend my laptop, (if I had an open qemu+ssh connection in virt-manager), when I resume I see dozens of dialog boxes with the error:

   Error polling connection 'qemu+ssh://user@host/system': 'NoneType' object has no attribute 'getInfo'

I would expect virt-manager to silently ignore this error (or try to detect whether or not I have a network connection) so that I don't have to dismiss dozens of dialogs. =)
