[gdal-dev] missing point in MultiGeometry KML file

[Greg Minshall]

hi.  i'm a newbie, trying to do some scripting which involves reading in
a KML file and then, after some processing, writing it out again.  i had
noticed that when running ogrinfo(1) on my input file, i wasn't seeing
all the point of the polygon in the MultiGeometry of my KML file, but
thought maybe that was just some form of abbreviation.  but, that
behavior seems to explain a problem i'm running into.  so, i tried
"ogr2ogr -f kml", and get the same behavior, my polygons are reduced to
a single point (the initial/terminal point).

i'm curious if it's obvious what i'm doing wrong, or if this is a known
bug, or...

my set up is a Mac running Fink:

a fairly reduced test case is running "ogr2ogr -f kml clone.kml bug.kml"
where "bug.kml" is:
