> C++ Broker deletes dynamic bridges too aggressively

> If a dynamic bridge's session has been detached while attempting to propagate
> a binding event, the broker will delete the bridge. Normally, a detached
> bridge session will be automatically recovered during the maintenance
> periodic if possible. Needless to say, auto-deleting the bridge upon a
> session error prevents this normal recovery path from occurring.
> This event can occur in a production system during broker startup/federation
> and also during source broker recovery since there is a potential race
> condition between creation of the source exchange and the creation of the
> dynamic bridge on the destination broker.
> Log Message:
> Sep 30 19:41:40 localhost qpidd[10497]: 2012-09-30 19:41:40 [Broker] error
> Cannot propagate binding for dynamic bridge as session has been detached,
> deleting dynamic bridge
> Steps to reproduce:
> # src broker: localhost:5801
> # dst broker: localhost:5803
> #
> # Create exchange in dst broker
> #
> qpid-config -b localhost:5803 add exchange topic fed.topic
> #
> # create dynamic bridge
> #
> qpid-route dynamic add localhost:5803 localhost:5801 fed.topic
> #
> # create dst queue as bind target
> #
> qpid-config -b localhost:5803 add queue fed.topic.queue
> #
> # create binding on dest exchange
> #
> qpid-config -b localhost:5803 bind fed.topic fed.topic.queue
> qpid-config -b localhost:5803 unbind fed.topic fed.topic.queue
> # The unbind should not delete the bridge.
