Comment (by mlennert):

 I think I found the issue.

 When running with g.gisenv set=DEBUG=1, I get:


 {{{
 v.vect.stats -p points=gc type=centroid areas=grid_one_cat points_col=col
 countcol=count statscol=sum method=sum
 [...]
 D1/1: 9 cats loaded from vector (including duplicates)
 D1/1: 5 cats loaded from vector (unique)
 [...]
 }}}

 There should be only 1 unique cat.

 The attached patch seems to solve this for me, but it needs testing and
 review.
