What does "WARN Could not determine content-length of response body." mean and how to I get rid of it?

Since upgrading to Rails 3.1 I'm seeing this warning message in my development log:

WARN Could not determine content-length of response body. Set content-length of the response or set Response#chunked = true

What does this mean and how can I remove it? Is it a problem?

    ya, it's fine. Need to clean it up, but nothing is being hurt.
