The parameter for v.db.addcol is columns='prova varchar(15)'. I don't 
think you can split that up into two parameters. Shouldn't this be:

vaddcol=subprocess.Popen('v.db.addcol','map=vect_1','columns=prova 
VARCHAR(15)')

?
(don't know if the white space is allowed as such or whether you need to 
quote the entire parameter as "prova VARCHAR(15)")
