Problem with xml pull syndication feed interface when node is used for two items in post

[justjames]

there is a small bug in the user interface for creating feeds. Sometimes you need to use the same node in the feed for two things in the post. Maybe the post title and also a post_meta for example. So... this is fine, as long as you enter the duplicate nodes LAST. If you make any change after you've entered and save, they get combined into one. Can you take a look at this and see if you see the bug that causes this to work this way?

Thanks,

James
