Request-response messaging over temp queues fails after no messages received from producer

Two bundles are set up in ServiceMix:

• a producer (pinger) that makes a request via a Camel inOut("activemq:...") and waits for a response
• a consumer (ponger) that pulls from that queue and responds on a temporary queue

When no requests are received from the pinger for a period of time (around 2 minutes), any ping calls subsequently fail with an exception on the ponger.
"Cannot publish to a deleted Destination: temp-queue://ID:..."

To reproduce, disable the ping timer route in the pinger bundle (attached in ESB-1573), and wait.
