Because it's not a bug!  the r300 drivers does not currently support
smooth lines in hardware so when a GL app calls for them they have to
be drawn with software.  You cannot just arbitrarily ignore certain
primitives.  Not drawing the line may not produce a noticeable
difference in googleearth, but it may in other apps.
