The type '-1' is wrong, it should be 1-8. The problem could be in 
grass51/lib/vector/Vlib/read_nat.c Vect__Read_line_nat():

   /* first byte:   0 bit: 1 - alive, 0 - dead
   *                1 bit: 1 - categories, 0 - no category
   *              2-3 bit: store type
   *              4-5 bit: reserved for store type expansion
   *              6-7 bit: not used
   */

....
   char rhead, nc;
....
   rhead >>= 2;
   type = dig_type_from_store ( (int) rhead );


the line can be deleted:
   rhead &= 0xFE;

but I don't know where is the problem. Maybe rhead should be unsigned?
