I just noticed that my RSS feed has additional text that W3TC appears to insert. http://feedvalidator.org/check.cgi?url=http%3A%2F%2Fwww.realworldtech.com%2Ffeed%2F is the validator check.
Everything looks fine up until:

Why is that text getting injected? I have feed caching enabled, but when I disable feed caching on my test system, the problems are still there.
Is there some setting I need to disable?
