New issue 122 by robe.... at cityofboston.gov: ST_SnapToGrid gives 13 when fed  
circular string
http://code.google.com/p/postgis/issues/detail?id=122

What steps will reproduce the problem?
1. 	SELECT ST_SnapToGrid(foo1.the_geom, 0.5, 0.5)
			
			FROM ((SELECT ST_LineToCurve(ST_Buffer(ST_SetSRID(ST_Point(i,j),4326),
j))  As the_geom
		FROM generate_series(-10,50,10) As i
			CROSS JOIN generate_series(40,70, 20) As j)) As foo1;


What is the expected output?
IT either works or says it doesn't work with curved polygons

What do you see instead?
ERROR:  lwgeom_grid: Unknown geometry type: 13

Happens in both 1.3 and 1.4SVN
