The only times I have seen that in the last 30 years has been a result of 
incredibly poorly installed blocks, or blocks that had had the tuning pins driven 
in without support,(pushing the bottom lamination down).  
     Also, if the crack is parallel to the ribs, it is not a crack, it is a 
rib separation.  If this is a new soundboard, somebody is in trouble.
