Sorry, ignore the above bugs.kde.org links. They were in reference to a
different bug.
This bridging problem still exists though. I have to put this in my
/etc/rc.local to get my bridge to come up on boot:
# Bring up br0 on boot because Debian bug:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=765000
if (egrep "^auto br0|^allow-auto br0" /etc/network/interfaces 1>
/dev/null) && [ -z "$(ip link | egrep "^[1-9]+: br0: " 2> /dev/null)" ]
; then
echo "WARNING: Had to fix up br0 interface at boot."
ifup br0
fi
