If you have a media picker on a content node, select a media item, save, then transfer via courier.

Now, if you delete the media item selected, save, and transfer via courier.

The source is fine, but on the target, you have a blank node selected (e.g. the delete link is there). In the database, the property value is null on the source, but 0 on the target.

I can adjust the xslt to check for this, but it is a bit of a problem...
