Log message:
cope with LOOP_THROUGH modifying the lis (queues).
in case of an error in the queue def in question the queues list remains
unmodified, but the LOOP_THROUGH caused a mod anyway, and the list can stay
empty. subsequent checks for NULL which check for a empty list fail then.
fix by adding an explicit check before looping.
