 I have some data that is correctly rendering as polygons but does not
 buffer correctly using the AJAX viewer buffer operation.  I have dumped
 the WKT of the feature:

 CURVEPOLYGON ((-123.94884211782004 49.168238831862574 (LINESTRINGSEGMENT
 (-123.94854780008535 49.168268848308159, -123.94825348198435
 49.1682988640056, -123.94829573817191 49.168477224793179,
 -123.94888439769528 49.168417203908902, -123.94884211782004
 49.168238831862574))))

 Buffering this geom results in a buffer that appears to be a circle around
 one point in the polygon (I didn't check but I'd guess its the first
 coordinate).

 I'm not sure what component to stick this in.  There isn't anything for
 the Geometry API so I'm sticking it in the feature service, please
 reassign as appropriate.
