Hi folks: I am trying to track down the (null) problem. I think it is mpiformatdb related, though I am entirely sure what it is yet. Could anyone who has been getting the (null) showing up send me a quick note offline (to email below)? If you have resolved it, even better. I would like to understand the cause of it, and I cannot seem to reproduce it.
