I created a feed using the Feed Builder, it worked fine for a while. Now when I try and access it I get an error on the Tomcat console:

2005-10-19 13:58:59,992 ERROR [atlassian.confluence.rss.DefaultFeedBuilder] Feed Error:java.lang.ClassCastException

Here is the feed URL:

http://evett1600:9999/createrssfeed.action?types=page&types=blogpost&types=comment&types=attachment&statuses=created&statuses=modified&spaces=&labelString=&rssType=rss2&maxResults=10&timeSpan=5&statuses=latest&publicFeed=true&title=AllAnon

I can't find anything more detailed in the logs.
