This is tough to replicate because it only happens once in a while... If I add a large amount of text to bodyText (e.g. more than several lines worth) to a /templates/standard.xml. Attempt to render, it may fail (I imagine a timeout or something like that.) However after removing all of that text and having no text in bodyText, it may fail to render normally (via queue). When this is the case a "force render" doesn't solve the problem either. After trying several different strings in bodyText, it was randomly able to render properly again.
