Ah. And it turns out that the bug fix I was talking about concerned
polygon exteriors (rings) being returned as linestrings. Disregard my
previous post.

Kurt,
A non-closed line segment has a boundary equal to a set of two
points. Linear rings (such as a polygon's boundary) don't have
boundaries. That's part of the definition of being a closed curve.
You're looking at a GEOS bug in which polygon boundaries are
returned as linestrings instead of rings. IIRC, Charlie Savage and
I closed that before the 3.0 release. Are you using a very old GEOS?
