 Priority:  major       |   Milestone:  Tor: 0.2.2.x-final
Component:  Tor Client  |     Version:

 If I run a bridge with
 {{{
 Address 128.31.0.34
 ORListenAddress 128.31.0.39
 }}}
 and then somebody runs their Tor client with
 {{{
 bridge 128.31.0.39
 }}}
 then it will connect, fetch the bridge descriptor, try to build a circuit
 by using 128.31.0.34, fail, and then sit there circuitless and bridgeless.

 This bug is important because it means if you run a multihomed bridge, all
 the clients will immediately switch to using its single canonical address,
 ignoring all the other addresses you configured. If that canonical address
 gets blocked, the other addresses don't matter even if they'd still work.
