I created an configuration file that would index only that one URL
and the htdig program still freezes with no core dump. I used -vvvvvvv as
you suggested and got the following output with the cursor just siting on
a line by its self at the end of these verbose comments:

It looks like it is hanging on the second META tag. As you have noticed, the
META tags do not use quotes around the content field which I believe is what
is causing the htdig program to hang.
