I seem to be able to use xn* interfaces with bridges without problems:
xn0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=3<RXCSUM,TXCSUM>
ether 00:16:3e:74:3d:76
nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
media: Ethernet manual
status: active
bridge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
ether 02:77:3d:4a:18:00
inet 172.16.1.140 netmask 0xffffff00 broadcast 172.16.1.255
nd6 options=9<PERFORMNUD,IFDISABLED>

Is this a GENERIC kernel or are you using some custom configuration/patches?
Can you provide some more information about how to reproduce this?
Roger.
