pygrass wrongly reports lines for point vector maps

[sbl]

Tested on both Windows and Linux. Here an example using NC data set:

v.info busstopsall_uncont layer=1 -t
nodes=0
points=108
lines=0
boundaries=0
centroids=0
areas=0
islands=0
primitives=108
map3d=0

So, no lines n the map. However, when I try to get the same info from pygrass, 108 lines are reported in addition to the 108 points:

from grass.pygrass.vector import VectorTopo
in_vect = VectorTopo('busstopsall_uncont', layer=1)
in_vect.open(mode='r')
in_vect.is_open()
True
in_vect.number_of('points')
108
in_vect.number_of('lines')
108
