No problem here but I found that's easier to not use network-bridge
script[1].

You can setup bridge interface in /etc/network/interfaces and configure
xend to use network-dummy script.
"(network-script network-dummy)" in /etc/xen/xend-config.sxp

Install bridge-utils and in /etc/network/interfaces put:
auto xen-br0
iface br0 inet static
        address ...
        network ...
        netmask ...
        broadcast ...
        gateway ...
        # bridge setup
        # eth0 -- outgoing NIC
        bridge_ports eth0
        bridge_stp off
        bridge_fd 0

Use vif-bridge script in domU configuration normally.

Back to your problem -- run commands (while dom0 network has problems):
# brctl show
# brctl showmacs xen-br0
# ip addr ls

Post results to mailing list.
