OK, see ofn-fit-canvas-to-path on 
https://sourceforge.net/projects/gimp-path-tools/files/scripts/

Actually a mix of Bodo's ideas and mine. First compute a rough bounding 
box using path coordinates, resize the canvas to this, then crop using a 
selection on the path for a tighter fit.

If you want to be able to add a margin just ask.
