An ArgumentNullException is thrown from
System.ComponentModel.TypeDescriptor.GetConverter (System.Type type) whenever
the DefaultModelBinder is used. 

Reproducible: Always

Steps to Reproduce:
1.Create controller with an action that would use model binding. ActionResult
Foo(int id, string bar) for instance.
2.Try to load /Foo?id=1&bar=text
Actual Results:  
Unhandled ArgumentNullException is thrown.

Expected Results:  
The string "text" should have been bound to the bar variable. 

I will attach a simple demo shortly.
