I'd be happy to supply a sample.  Can you suggest a way to get it to you?

The best way would probably be to file a bug at

      http://bugs.wireshark.org/

I can do that but wanted to point out that there are three ways to run iptrace.

One is just iptrace.  Wireshark knows how to use those file just fine.

Second is iptrace with -B.  This is where the problem arises.  -B uses the bpf filter from tcpdump but formats the 
output as an iptrace file.  This  is where we see the problem.

Third is iptrace with -B and -T.  Wireshark knows how to handle this file too.

It seems probable that this is an AIX bug.  I want to investigate this a little more to make sure the three statements 
above are correct.
