Comment(by jng):

 I think this is a bug in 2 areas:

  1. MapGuide's KML renderer.
  2. The default redline style settings for lines.

 The line string geometry is there, but the style generated for it uses
 line width of 0 (assuming no changes from the default redline style),
 causing nothing to be drawn.

 The default style uses a 0 line thickness. The default image-based
 renderers in MapGuide seem to clamp 0 line thickness to some very small
 value > 0 (which is why we still see such lines being rendered), but the
 KML renderer does not and writes the thickness value as-is.

 Workaround is to specify a non-zero line thickness as a default, proper
 fix is to make the KML renderer follow the same behaviour as the image-
 based renderers for dealing with 0 line thickness.
