Description

A backup creates an UpdateTracker to delete non-existent queues at the end of an update, in the UpdateTracker destructor. However if an update is interrupted, it can leave a partially-used UpdateTracker behind. When the next update starts this can incorrectly delete queues at a sensitive moment and cause a crash.
