[Mono-osx] ConfigurationErrorsException loading user settings (duplicate key)

[zidjian]

Hi all,

I have daveloped an .NET Application with Visual Studio 2005 and was trying
to launch it on MACOSX using mono.
Anyhow the application cannot load the configuration file correctly and says
the configuration has duplicate entries althought it hasn't.

Hope anybody can help me out here, as I couldn't find something on web
according to this problem.

Here is the StackTrace:

Unhandled Exception: System.Configuration.ConfigurationErrorsException:
