Blank description field defaults to another random item's title with common syndication parser

As per the title follow these steps to reproduce

1. Fresh Drupal install with only FeedAPI, FeedAPI Node Process, FeedAPI Common Syndication Parser enabled
2. Create Feed to a Delicious RSS URL, for example http://feeds.delicious.com/v2/rss/drupal?count=15
3. Import the feed items
4. Note that the title of one of the items will be used as the body for a number of other items.

This can be resolved by using SimplePie, but I haven't been able to solve it using Common Syndication Parser.
