OK, try the following steps:

- change the error message in OpenExeConfigurationInternal()
   in the first "throw ArgumentException" in ConfigurationManager.cs
   in mcs/class/System.Configuration/System.Configuration, to
   whatever you like.
- Rebuild all, and install
- Run your application and make sure that your change is reflected.

Your stacktrace is indeed weird to me. There is a line

 > 
System.Configuration.ClientConfigurationSystem.System.Configuration.Internal.IInternalConfigSystem.GetSection 
(System.String configKey) [0x00000]

which indicates that it invokes a method in an *interface* without
any implementation class information. It makes me impossible to
precisely keep track of the actual code execution (I haven't
ever experienced such a situation).

There is nothing other than ClientConfigurationSystem that invokes
OpenExeConfigurationInternal(), thus I can only guess that the
invoker is ClientConfigurationSystem, which uses GetCallingAssembly()
which you said does not return null.
