You don't need dead-lettering for this scenario. If Application B
crashes while processing an unacknowledged message then that message
will be returned to the queue and will be redelivered when Application B
restarts.

See the section on message acknowledgement in the second tutorial at
http://www.rabbitmq.com/tutorials/tutorial-two-python.html

Dead-lettering is applicable when a message is rejected with the requeue
flag set to false; or if a message expires.
