Sorry about the delay ;)
I don't know exactly what went wrong with this config file but what eventually goes wrong is a type casting attempt in ExeConfig line 194. ExeConfig tries to guess the type of a parameter from its default value. In this case this gave the type NoneType which should never be used. I am now eliminating NoneType from the list. Should work but not tested with this particular file.
