Exception: IllegalArgumentException: Invalid number of points in LinearRing found 3 - must be 0 or >= 4 in GEOSWKTReader->read()

(line 38 of /path/to/module/geophp/geoPHP/lib/adapters/WKT.class.php).

We have some code that is importing shapefiles and kmls. Both the kmls and shapefiles import properly on my local dev instance, where I do not have geos php extension installed. On prod, stage, and dev, this exception causes the import of shapefiles or kml to fail.

I can't post the shapefiles or kmls here but could send them directly if that could help with testing.
