Thanks for the report, fixed and uploaded new version.
The problem was not that much the lone anchor (you can have visible strokes with a single anchor) but the null length (which is strangely reported by Gimp has being a negative length).
Behavior remains "peculiar" with strokes that are much shorter than the period, but if you don't want them you can use ofn-path-filter-strokes to remove them.
