Thanks for reporting this bug. In part it appears to be a dup of bug 929382. However, the dpkg log shows that brctl addbr lxcbr0 failed because lxcbr0 already existed. Had you created lxcbr0 by hand? If so, then the lxc init script should simply detect that and quietly exit (without destroying it). If not, then there is a question of why the /etc/init.d/lxc did not destroy lxcbr0 when it was stopped at the start of the package update.
