I may be misunderstanding you but it sounds as though you are trying  
take a layer from one image and add it to another image directly. You  
actually have to create a duplicate of the original layer (using  
'gimp-layer-new-from-drawable') and then add the duplicate to your  

Since just transferring a layer from one image to another should  
result in a PDB error, I suspect that I may have completely  
misinterpreted your steps (perhaps you could provide the full code).
