OGRSFDriver::CreateDataSource creates data source with NULL driver

[amagnum2@…]

I use CreateDataSource to create several shape files layers in a folder, or to create tables in PGSQL.
I get an instance of the SHAPE driver, and then I specify in the name paramater the relative path of the folder, then I issue CreateLayer to create the shape files.
When I use OGRSFDriverRegistrar::Open on the same directory with shape files the driver pointer is attached.
When I use OGRSFDriver::CreateDataSource the driver (fetched with GetDriver()) is NULL.

What's more interesting is that it still crates the layers properly even though the driver is NULL :)
