Creation of new financial batch fails

4.3 upgrade needs to change civicrm_batch.item_count column constraint to allow NULL (this column's constraint was set as REQUIRED in 4.2).

---- Original Post —
When I click "Contributions ... Accounting Batches ... New Batch", then fill in just the batch name and click save, I get an sql error. ( I am leaving all the optional fields blank)
