TypeDescriptor.GetProperties fails on an interface type.  Works in 1.9.

For instance:
   TypeDescriptor.GetProperties (typeof (IComponent));
fails with
[[
Unhandled Exception: System.NullReferenceException: Object reference not set to
an instance of an object
 at System.ComponentModel.TypeInfo.GetProperties () [0x0002a] in
D:\cygwin\usr\src\mono\mcs\class\System\System.ComponentModel\TypeDescriptor.cs:1164 
 at System.ComponentModel.Info.GetProperties (System.Attribute[] attributes)
[0x00000] in
D:\cygwin\usr\src\mono\mcs\class\System\System.ComponentModel\TypeDescriptor.cs:952 
 at System.ComponentModel.TypeDescriptor.GetProperties (System.Type
componentType, System.Attribute[] attributes) [0x00000] in
D:\cygwin\usr\src\mono\mcs\class\System\System.ComponentModel\TypeDescriptor.cs:733 
 at System.ComponentModel.TypeDescriptor.GetProperties (System.Type

]]

Apparently Type.BaseType of an interface type is null, the loop in
TypeInfo.GetProperties need to also terminate when at an interface -- or just
only on null.
