but when I just did a -T4 -vvv --traceroute, it works fine.

any idea or what we might try to hunt down the problem?  My brain
stopped working a few hours ago.

Did you use -T4 with -A?  Does --traceroute work without -T4?

Can you find the minimum arguments that can reproduce this problem? 
Will just 'nmap --traceroute <host>' do it?

I will do some testing today and let you know.  --traceroute works.  -T4 
and -A together caused the problem.  I'll not use -A and see if I can 
figure out the exact combination that causes the issue.
