virt-manager fails to detect the bridge with bond enslaved

Issue

virt-manager doesn't list the bridge devices(br0) in the "Advanced options" section when a bond interface is attached to it.

For example, create a bond device ( bond0 = eth1+eth2 ) and attach it to a bridge, br0

# brctl show
bridge name bridge id       STP enabled interfaces
br0     8000.c81f66d066ad   no      bond0
virbr0      8000.525400700906   yes     virbr0-nic

Then open virt-manager GUI and try to create a VM using this bridge. Ideally the virt-manager should show up 'br0' device
in the drop down list like  "Host device bond0 ( Bridge 'br0' ) , but this device doesn't appear in the device list.
