Unhandled Exception, No default tax provider

Running new source code in debug mode for first time. Navigating to any category results in the following error. I suspect this means I have to go into the admin to select a tax rate or something.  However, the system should probably handle this condition more gracefully. Maybe the default tax provider is not being loaded correctly.

Line 235:
Line 236:            //get tax rate
Line 237:            var calculateTaxResult = activeTaxProvider.GetTaxRate(calculateTaxRequest);
Line 238:            if (calculateTaxResult.Success)
Line 239:                return calculateTaxResult.TaxRate;
