This message contains the responses to two previous messages:
In response to Steven B.,the statements
Raw_packet_queue = enqueue(..., Raw_packet_queue, ...)
print 'Sort 1 Raw_packet_queue is', Raw_packet_queue
produce the output
Sort 1 Raw_packet_queue is [[(<Pkthdr object at 0x4341d7d0>,

This consists of two lists [[pcap packet header, pcap packet body], [a
list of selected IP header fields]]. Raw_packet_queue[0][0][1] should
return the 'pcap packet body' list element.
In response to Steve H., the traceback is
