v.db.connect -p says that no table is connected, in general I know 
nothing about mrog_5 I have never create it.
adationally when I tried to add empty table the same message appear
I remove the vector and import it again, I thing it was accident error 
due to some unknown circumstances, but why v.to.points became crazy?
