[Gimp-user] script to delete layer

[free <freewanderer rocketmail com>]

Hello to all! Again I am stuck with a problem with python script. I want 
to delete a layer, not only remove it from the image. The reason I want 
to do that is because while the script I did is running gimp increasily 
takes more and more memory, until a point that the script stops because 
there is no RAM left. My script duplicates layers, put them in the 
image, duplicate the image, exports and them removes the duplicated 
layers and image from it. But it seems that only removing the layers is 
not enough to liberate memory. Any help would be appreciated...

the pdb.gimp_item_delete function takes an item as parameter. So here 
is, more or less, what I am doing:

layer_to_be_deleted = gimp.Item.from_id(layer_id)
pdb.gimp_item_delete(layer_to_be_deleted)

This script cause this error:

Traceback (most recent call last):
  File "<input>", line 1, in <module>
RuntimeError: execution error

I don't know what is going on. I am running gimp on a windows xp x64 sp2.

In the documentation, it says that the item can not be in the image when 
the function is called. But if I remove it from the image and then try 
to delete it, I get this error:

Calling error for procedure 'gimp-item-delete':
Procedure 'gimp-item-delete' has been called with value '25' for 
argument 'item' (#1, type GimpItemID). This value is out of range.

wich is expected, because the layer_to_be_deleted layer is not an Item 
anymore. It changes to a null, I think.

Well, if someone have some other tip on how can I make the script stop 
taking all the RAM memory of my machine, it would be very appreciated :)
