Thanks for taking the time to report this bug. Certainly as root you should be able to attach devices to lxcbr0.
Could you please
1. show the result of 'ifconfig -a' and 'brctl show'
2. do 'sudo lxc-start -n Ubuntu-12.04.5-i386 -f -l trace -o lxc.debug' and attach lxc.debug here
3. try:
sudo lxc-create -t download -n p1 -- -d ubuntu -r trusty -a i386
sudo lxc-start -n p1
and let us know whether that succeeds.
