Repro sources

The attached repro shows a simple class derived from ConfigurationSection which
exposes a property marked with a TypeConverterAttribute instance defining a
custom type conversion to perform when reading the property's value from the
program's configuration file.

Run under Mono this program throws the following exception:

Unhandled Exception: System.MissingMethodException: Method not found: 'Default
constructor not found...ctor() of Trac102.MyPropertyConverter'.

  at System.Configuration.ConfigurationManager.GetSection (System.String
sectionName) [0x00000] 
  at Trac102.Program.Main (System.String[] args) [0x00000] 

If I make the constructor public then the program runs as expected generating
the output "my-property = correct".

Under the CLR this program will work with an internal constructor.
