Shorten URL not working if bit.ly is primary shortener and "use www instead of http" is selected

I have Shorten URL module enabled and configured to use bit.ly as the primary shortener. I have confirmed that the module has in fact created a shortened URL for the page in question. But when a service link is clicked, no URL (long or short) is being displayed. If I turn off Always use short links, the full URL is output. If I turn How generate short links to use node/xxx alias, that works as well. It only does NOT work when Use Short URL service is selected. If I disable Shorten URL, it works using the default tinyurl link.
