When using the library 'Json2.js'¹ the call 'JSON.stringify("some string")' generates an error saying "Invalid argument".

This issue does not appear in Firefox 3.0.x.

In this example² it first try 'JSON.stringify(["OK"])' which works and then it will try 'JSON.stringify("KO")' which generate the above error.
