Tinymce is incompatible with jquery ajaxsetup datafilter

Question

I use the following datafilter option on my jquery ajaxsetup:

    dataFilter: function(data)
    {
        var msg;
        if (typeof (JSON) !== 'undefined' &&
        typeof (JSON.parse) === 'function' &&
        data != undefined &&
        data != null &&
        data.length != 0 &&
        data != " ")
            msg = JSON.parse(data);
        else
            msg = eval('(' + data + ')');
        if (msg.hasOwnProperty('d'))
            return msg.d;
        else
            return msg;
    },

When I put this in $.ajaxSetup({,, tinymce is not initialized in my text box (it just shows the original text box as if tinymce is not set). If I move this filter to the actual ajax calls, I have no problems, and everything is fine. Notice that I'm doing everything I can save in a .axx file with ajax support, and it works fine.

jquery 1.4.3, tinymce jquery version 3.3.9.2

Why can the ajaxsetup parameter for a data filter cause tinymce to not work?
