Fixed upstream now:

http://hg.fedorahosted.org/hg/virt-manager/rev/0ade95843eba

virt-manager was trying to create a guest with no network device
attached, which means it couldn't detect anything to use as the network
source (either a libvirt virtual network, or a bridged NIC). So just an
FYI, even though the bug is fixed, your new guests won't have any
networking.
