Andrea - try this in the Spearfish sample.
v.delaunay bugsites output=delaunay -l
- This kind of output produces the same issue that you're having.
v.to.points -v delaunay output=delpoints
- This creates point at line vertices, with a database connection on
layer 2. The database includes "along", which is how far the new point
is along the line. Since the points are at the vertices, this should be
the same as the line length.
db.describe delpoints_2
v.db.select delpoints layer=2
Cheers,
Richard

just to make it clearer.... if I do the above steps with v.delaunay, then I
create the table with v.db.addtable and then I run v.category, it works
fine.
If I do the same steps with v.delaunay with the -l flag (and I have to,
since I need the lines), then it doesn't.
cheers
