gimp 1.2

Hello
I'm running dsl on a Pentium 3, 666mhz processer with 356mb on RAM.
I want to copy a layer on a series of jpg-images (that I saved from a video in avidemux) , but everytime I open a bash and type: gimp -b[]file> , it says "batch command experienced an execution error".
I'm having Gimp 1.2 from out of the "mydsl" directory, and normaly this should work with video->frames modify->duplicate layer, i think. But it will not.
Maybe someone can help me out here.

Hello again
Is there anyone who can run batch mode from gimp in dsl anyway?
It can't be so difficult, I think it must be a (java)-script like a project in Avidemux.

In the meanwhile I have installed Python from Synaptic, together with a script from the net (recipe 496897-1.py) , but they do'nt seem to match totally.
Maybe someone can hand me a plug-in, module, or script with instructions to make it binary and install it to usr, lib, gimp, ...

Thanks.

I found the solution myself already.
In the menu "video=>move paths" I can do exactly what I wanted.
