filefield delete image default field from drupal files folder.

How to get this bug:

first build a new content type. It's very important that the content type must bee new, and make the steps with the first node.

Add an imagefield field with a default image.
Add a filefield

first step:
* Create the first node.

* The node will be see ok.

Second step:

* Remove the image.
* Save the node.

Or

first step:

* The node will be see ok.

Second step:
* Edit the node.
* Remove the image.
* Add a new image.
* Save the node.

Thirsth step:
* Edit the node.
* Remove the image.
* Save the node.

In both case the default image is delete from the node and from the files folder, but the image field default configuration is looking for it.

If you save the first node with the default image, and them delete o try to make the same with the second node or another one the image is not delete.
