Android - Uncaught Error: Index -1

Well, i have this annoying problem, every time i call a function to request data from SQlite database, when the request is empty, the App stop working. In iOS works flawless, but in Android don't.

This is the code:

validarLogin: function(e) {
        var _db=Ti.Database.open('database');
        statusLogin=_db.execute('SELECT * FROM Usuario WHERE logged=1');
        alert(statusLogin);
        var status="";
        if(statusLogin!=null){
            status={
            logged:statusLogin.fieldByName('logged'),
            consultor:statusLogin.fieldByName('idConsultor'),
            type:statusLogin.fieldByName('type'),
            };
        }
        _db.close();
        return status;
    },

And the error is this:

Uncaught Error: Index -1 requested, with a size of 0.

Thanks for your help.
