No, my crawler does nothing but load the page - does not follow or index any links.

I have noticed there are some old profiles that still have an avatar from an external source, and they time out when I try to connect.  Examples:
https://bitcointalk.org/index.php?action=profile;u=3758
https://bitcointalk.org/index.php?action=profile;u=5153

I feel this is somehow related to that issue.
