Jeremy, It seems to me that using Gimp for this task is perhaps not the best use of Gimp or of your time. I do not know the specific answer to your question about the problem you are encountering, but perhaps a program such as ImageMagick http://www.imagemagick.org/script/index.php would be more suitable. ImageMagick is specifically designed to do the kind of batch tasks that I believe I understand you wish to accomplish. We use it to process tens of thousands of images (making multiple sizes of JPEGs from TIFFs), but I don't have any specific experience with the task you are attempting.
