Hi, Same crash here: POSTGIS="1.5.2" GEOS="3.2.2-CAPI-1.6.2" PROJ="Rel. 4.7.1, 23 September 2009" LIBXML="2.7.3" USE_STATS PostgreSQL 9.0.1 on x86_64-apple-darwin10.4.0, compiled by GCC i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5664), 64-bit
JTS also fails to validate it (in OpenJump) The buffer(0.0) trick seems to correct the polygon, transforming it to a Multi PG: select st_buffer(polygon, 0.0); It is then valid.
