[GRASS-user] Unexpected result with v.net op=connect. No attributes on new lines.

Hi all,

I'm doing some basic exercises based on v.net on GRASS GIS but I'm 
getting some unexpected results (according to my knowledge and my 
understanding of the v.net manual). When I execute the following command:

v.net input=streets_clean points=libraries output=network 
operation=connect threshold=50

I get unsatisfactory results according to the v.net manual: "While the 
arcs created with v.net will retain any attribute information associated 
with the input vector line/boundary file in data layer 1, nodes created 
and stored in data layer 2 will not have any associated attribute 

The problem is that the new created lines connecting the points 
(libraries) to the existing network (streets_clean) doesn't retain 
neither show any kind of attributes. There is a new geometry with no 
attributes associated. As far as I remember, older GRASS GIS versions 
(6.4.x) worked well on this issue.

Any hints?

My GRASS GIS version on gnu/linux:

I've already tested a Windows version with the same results
