Subject: r.to.vect: -v flag doesn't transfer cat values

Hi,

If I make a stream map with r.watershed,
then 

r.null rwater.stream setnull=0
r.to.vect -v in=rwat.stream out=rwat_stream feature=line

Extracting lines ...  100%
 100%
Building topology ...
17 primitives registered      
Building areas:  100%
0 areas built      
0 isles built
Attaching islands: 
Attaching centroids:  100%
Topology was built.
Number of nodes     :   24
Number of primitives:   17
Number of points    :   0
Number of lines     :   17
Number of boundaries:   0
Number of centroids :   0
Number of areas     :   0
Number of isles     :   0
r.to.vect complete.


the vector map is created but the lines have no cats
v.info:
 |   Number of dblinks:      0     

the input map is CELL, raster range is min=2 max=64.
the -v flag was used with r.to.vect.

G63> db.connect -p  
driver:dbf
database:$GISDBASE/$LOCATION_NAME/$MAPSET/dbf/
schema:(null)
group:(null)


?

thanks,
Hamish
