Found the root cause - I am creating the Manufacturers programatically and PageSize is defaulting to 0 - but guys we need to be checking for this condition

Great learning here - as I've run into multiple issues trying to programatically add a ton of records:  because of the EntityFramework and Code First model, the application handles defaults just fine - but if you're trying to build an import application for a specific product feed - you need to make sure all the defaults are set when adding entities.  It would help if the "default" values were setup in the DB as well so that if omitted from an add statement - they'd refelct the same values as if adding from the admin panel.
