Might be.  I don't see anything on the issues tracker:
http://code.google.com/p/gmaps-api-issues/issues/list?can=2&q=apitype:Javascript+polyline+&colspec=ID+Type+Status+Introduced+Fixed+Summary+Internal+Stars&cells=tiles

If I encode the polyline using this page:
http://facstaff.unca.edu/mcmcclur/GoogleMaps/EncodePolyline/encodeForm.html

 it works:
var polyline1_1 = new GPolyline.fromEncoded({
  color: "#0000ff",
  weight: 4,
  opacity: 0.8,
  points: "[EMAIL PROTECTED]|
[EMAIL PROTECTED]",
  levels: "PKGHFNKLP",
  zoomFactor: 2,
  numLevels: 18
});
map.addOverlay(polyline1_1);
