Gimp script-fu有时只工作

Question

我不是真正精通图形的人之一，所以我在interwebz上发现了这个脚本，它有点碰壁了

(
define (script-fu-pcb-filter img)
(gimp-image-convert-grayscale img)
(gimp-image-flip img 1)
(gimp-image-resize img (* (cadr (cddr (gimp-selection-bounds 1))) 2) (* (caddr (cddr (gimp-selection-bounds 1))) 2) 0 0)
(gimp-layer-copy 2 1)
(gimp-image-add-layer img 3 0)
(gimp-layer-new img (cadr (cddr (gimp-selection-bounds 1))) (caddr (cddr (gimp-selection-bounds 1))) 2 "druhy" 100 0)
(gimp-image-add-layer img 4 0)
(gimp-edit-fill 4 2)
(gimp-image-lower-layer-to-bottom img 4)
(gimp-image-merge-down img 2 0)
(gimp-selection-all img)
(gimp-flip 5 0)
(gimp-floating-sel-anchor 6)
(gimp-selection-all img)
(gimp-flip 5 1)
(gimp-floating-sel-anchor 7)
(gimp-flip 3 1)
(gimp-image-merge-down img 3 0)
(gimp-convert-indexed img 0 3 0 FALSE FALSE "a")
(file-png-save 1 img 8 "/tmp/etch_eagle_export.png" "/tmp/etch_eagle_export.png" FALSE 9 FALSE FALSE FALSE TRUE FALSE)
)
(script-fu-register "script-fu-pcb-filter"
"PCB-Filter"
"Gets ready export image from egale ready for print"
"Anton Krug "
"Anton Krug"
"2009-04-25"
"RGB*, GRAY*, INDEXED*"
SF-IMAGE "Input Image" 0)

(script-fu-menu-register "script-fu-pcb-filter" "/Image/Eagle/")

它应该翻转图像并对其进行镜像，以便在一个页面（A4目的地）上获得相同图像的两个副本，并且图像应保留其原始比例，即不进行任何大小调整。然后将图像打印在透明胶片上并用于蚀刻pcb。

我将脚本保存在正确的文件夹中，当我使用干净的数据文件夹启动gimp时（在我的案例中为/home/foo/.gimp-2.8），脚本运行正常，一次。关闭第一张图像后，甚至在重新启动gimp后，我无法再次在另一张图像上运行该脚本。我必须删除gimp的数据文件夹并将其重新保存在脚本文件夹中，以便脚本再次运行。这有点超过脚本imho的目的所以我想知道为什么它现在按预期工作。有什么我想念的吗？

编辑：错误消息＆amp;附录

附录：当我从新的配置文件文件夹刷新脚本时，菜单项PCB-Filter显示2倍。我正在运行manjaro，这是arch linux的衍生产品，gimp -v给出了：
