If this happens with GRASS 6.x, I think the expected output can be obtained by adding the -c flag: Export features with category (labeled) only. Otherwise all features are exported
v.out.ogr type=line input=esw_g26a format=KML dsn=main.kml layer=7 -c The meaning of the -c flag has been reverted in GRASS 7 to avoid cases like these.
