Hey guys,

I'm using a server running libvirt 0.8.2 and my desktop running
libvirt 0.8.2. My desktop has virt-manager 0.8.4 and I've got a Linux
VM running on the server. I'm looking to use the new migration support
to migrate the VM to my desktop from the server. Everytime I attempt
the migration I get an error dialog containing the following (I've
actually snagged this out of ~/.virt-manager/virt-manager.log
