Ok here we go.

1) first attempt:
GRASS 6.1.cvs (tx_state_nad83):~ > r.to.vect in=test out=test_vect
crowded cell 6H (1,238) -continuing
crowded cell 6H (1,239) -continuing
crowded cell 6H (1,240) -continuing
update_list:  crowded cell 7H (1,244)
ERROR: cell file is not thinned properly.
        Please run r.thin

2) thinning:
GRASS 6.1.cvs (tx_state_nad83):~ > r.thin in=test out=test_thin

3) second attempt after thinning:

Even though I get the error, a vector file (test_vect) is still  
created. However, if I attempt to display that vector, I get the  
following errors:

GRASS 6.1.cvs (tx_state_nad83):~ > d.vect test_vect
WARNING: coor files of vector 'test_vect at PERMANENT' is larger than it
          should be (151584 bytes excess).
