Comment(by Sebastian):

 I think nickm is right, we do seem to check that we don't cache private
 addresses in all cases where it matters, except in the case where we ask
 to resolve a private address directly (here we'd warn anyway). Isn't it
 more likely that you were accessing a resource that actually tried loading
 content from a private IP address? Trying to connect to "localhost" seems
 to confirm that.

 This actually led me to discover two more issues: We don't ratelimit the
 log message, so a website that tries to include a lot of local content can
 easily spam your log. And if someone asks to resolve localhost, we ask a
 lot of exits before accepting that we don't get an answer we'll like.
