Overlapping Paths

[Ofnuts]

By the way, in your workflow when you transfer the path back from Inkscape, the problem is that the position of holes gets wrong somewhere in along the way. So did you try to export as SVG from Inkscape and import the file in Gimp instead? If the technique works then you are more or less sorted, and if the problem persists the SVG is a smoking gun: if the coordinates are incorrect it's Inkscape's fault, otherwise it's Gimp's.
