Cloning nodes with imagecache fields should create a copy of the image

I have just found to my cost that cloning nodes with an upload field has a serious pitfall - the cloned node references the original image, which means that if you delete it, the original node loses it's image too. It really ought to create a copy of the upload (I would have thought, anyway).

I'm going to try and produce a patch to get round this as it a show-stopper for a site which I have due to go live shortly, but I'm flagging the bug up in case anyone an offer any advice or has maybe already had to get round it.
