SFCGAL doesn't specify unknown type when dealing with curves

[robe]

Minor issue but:

ST_3DDifference returns:

ERROR:  LWGEOM2SFCGAL: Unknown geometry type !

With curved surfaces - a query such as:

SELECT ST_3DDifference('POLYHEDRALSURFACE Z (((-72.2 41.755 0,-72.2 41.755 1,-72.2 42.755 1,-72.2 42.755 0,-72.2 41.755 0)),((-72.2 41.755 0,-72.2 42.755 0,-71.2 42.755 0,-71.2 41.755 0,-72.2 41.755 0)),((-72.2 41.755 0,-71.2 41.755 0,-71.2 41.755 1,-72.2 41.755 1,-72.2 41.755 0)),((-71.2 42.755 0,-71.2 42.755 1,-71.2 41.755 1,-71.2 41.755 0,-71.2 42.755 0)),((-72.2 42.755 0,-72.2 42.755 1,-71.2 42.755 1,-71.2 42.755 0,-72.2 42.755 0)),((-72.2 41.755 1,-71.2 41.755 1,-71.2 42.755 1,-72.2 42.755 1,-72.2 41.755 1)))'::geometry,'	MULTISURFACE(CURVEPOLYGON(CIRCULARSTRING(-71.0821 42.3036,-71.4821 42.3036,-71.7821 42.7036,-71.0821 42.7036,-71.0821 42.3036),(-71.1821 42.4036,-71.3821 42.6036,-71.3821 42.4036,-71.1821 42.4036)))'::geometry);

Same issue with ST_3DUnion
