WebKit doesn't seem to like a jQuery script with two separate functions bound to the click event

Question

I have a couple of functions bound to the click event for a link.

//submit forms when links are clicked
$("a.submit").click(function(e){
    e.preventDefault();
    $("form").submit();
});

and:

//turn this off in webkit for now
//if (!$.browser.webkit){
    $("a.btn").click(function(e){
        //if this is a submit or a save button
        if ($(this).hasClass('submit') || $(this).hasClass('save')){
            //check if there were validation errors
            if(validator.numberOfInvalids()===0){
                //only switch out the link if there weren't any
                btn_ajaxload($(this));
            }
        }else{
            btn_ajaxload($(this));
        }
    });
//}

btn_ajaxload() replaces the entire <a> element with an ajaxload image. It works as expected in Firefox, IE6, IE7 and IE8 but I cannot get it to work in Chrome or Safari. If I comment out the first function's $("form").submit() line then the 2nd function works, but I can't get them both to work together.

The solution I'm leaning towards is to merge the two functions together but I'm wondering if there's a reason why it doesn't work in WebKit browsers?
