Problem with two or more Imagefields with default image: node seems to have default images uploaded

Using FileFields Paths makes default image to get attached to node same way as if they were uploaded to the node when no image is uplaoded. So, when image from node is deleted (to upload the right one) default iamge file is deleted. This only happens when using two image fields.

Steps to reproduce:

1) Set up a content type with two image fields with just one value each (so you only can upload one image per field) using a default image that is uploaded when content type is created (one image for each field).

2) Create a new node of that content type without uploading any image. When node is accessed the default images are shown.

3) Edit that new node. the two iamge fields are empty. Upload an image in one field, leaving the second field empty. When node is accessed first field shows the uploaded image and second field shows the default image. All right for now.

4) Edit again that node. The first field shows the uploaded image, but the second image field is not empty, it shows the default image just as the same way if it that image was uploaded to this node (what it hasn't been done)

5) Push delete button to upload the right image for this node to substitute the default image. But this action makes the original default image file to be deleted.

Disabling FileField Paths works as expected: in 4) the second field is empty, so you can upload your new image withuot problems.

I didn't have time enought to check code or look deeper, any new info will be posted here.
