I have a similar bug. lubuntu 12.04. If I add in the config bridge br0
/etc/interfaces # The loopback network interface auto lo iface lo inet loopback
# The primary network interface auto eth0 #iface eth0 inet dhcp iface eth0 inet static address 10.0.1.8 netmask 255.255.0.0 gateway 10.0.0.9
auto br0 iface br0 inet static address 192.168.0.10 network 192.168.0.0 netmask 255.255.255.0 broadcast 192.168.0.255 gateway 192.168.0.1
normal boot without a bridge
