jQuery warnings in Firefox Error Console

Question

All of the sudden, I'm getting a bunch of warnings in the Firefox Error Console... this wasn't happening earlier today, and I haven't made significant changes. The error is just constantly repeating and accumulating about 3-4 times a second:

Warning: reference to undefined property jQuery.ajaxSettings.traditional

and that points to line 5383 of jQuery.js which is the jQuery JavaScript Library v1.4.2 file that I include. This is the only new code I added today:

$(document).ready(function(){
    // search field focus and blur event handlers
    $('#search-field').focus(function() {
        if($(this).hasClass('placeHolder')){
            $(this).val('');
            $(this).removeClass('placeHolder');
            $(this).addClass('search-field');
        }
    });
    $('#search-field').blur(function() {
        if($(this).val() == '') {
            $(this).val('Search');
            $(this).addClass('placeHolder');
        }
    });
});

So when I put this code in its own file separately... I get the following warnings:

Warning: reference to undefined property E.queue

Warning: anonymous function does not always return a value
   Source File: http://localhost/jQueryChat/js/jQuery.js
   Line: 404, Column: 2
   Source Code:
        }, 

Warning: anonymous function does not always return a value
   Source File: http://localhost/jQueryChat/js/jQuery.js
   Line: 416, Column: 23
   Source Code:
        return jQuery.ready(); 

.. and such. So I don't know why this is happening. Any ideas?

UPDATE: I went to about:config for Firefox and turned javascript.options.strict to false and the warnings went away. But I feel like this is not a solution.

Thanks, Hristo
