Subject: network namespace + bridge visibility

==========================
mmarkk@...c:~# brctl addbr qwe
mmarkk@...c:~# unshare -n /bin/bash
root@...c:~# ip link
14: lo: <LOOPBACK> mtu 16436 qdisc noop state DOWN

root@...c:~# brctl show
bridge name bridge id STP enabled interfaces
qwe 8000.000000000000 no
root@...c:~# brctl delbr qwe
bridge qwe doesn't exist; can't delete it
=============================

So, network device is not available, but present in list of bridges.
This is the bug, as I think.

Reproducible in linux kernels 3.8.2 and 3.2.0
