That suggests you've got another script with a problem! Do you want another go round the loop? If so attach the latest version of duplicate_scripts.txt, or have a look at it yourself.
Last time the end of the file was this:
Finished with C:\Users\Molly\.gimp-2.8\scripts\Path_selection_sum.scm
C:\Users\Molly\.gimp-2.8\scripts\Pattern from Image(1).scm
define script-fu-pattern-from-image
script-fu-register script-fu-pattern-from-image
script-fu-menu-register script-fu-pattern-from-image
gimp-image-resize-to-layers image
set! image-layer
gimp-drawable-set-name image-layer
plug-in-autocrop too complicated!
gimp-image-scale-full image
set! patternImage
set! pattern
set! fileName
file-pat-save too complicated!
gimp-image-delete patternImage
list inName
gimp-patterns-refresh
So you can see how I knew it was "Pattern from Image(1).scm" causing the problem.
