Dave,

You never really explained what the problem was.  What error were you 
getting, and what does this fix solve?

Also, the patch you have sent reports the entire file as being changed. 
    That is not useful to review.  Can you send a followup to the list 
with a better explaination and a patch that can be more easily be reviewed.

thanks,
--Barry
