I have a problem using v.proj. In in the destination location the vector map is incomplete, it seems that the topology is not completely built. In particular, there are missing polygons. The command line:
Building topology for vector map <suolo_paes_ext>…
Registering primitives…

I’m using Debian, and tried both with grass6.4 debian package and grass6.5 svn
I also tried to use v.build after that, without results.

You are reprojecting from UTM_32_ED50 into ...?

In any case, you may need to clean up the topology *before* running v.proj.
Perhaps the original map isn't clean.
and imported the reprojected map with v.in.ogr. All polygons are reprojected now.
But I noticed that using v.proj the map was reprojected with an important error .I have another map of the same area, when I try to overlay them they are in two different places, very far apart. But when I overlay the map reprojected with ogr, everythings looks OK.
Couldn’t it be a bug of v.proj? Has anyone had a similar problem using v.proj?
