Cloning fieldset with jQuery without keeping value for input type file

Question

How can I remove the value for an input of type file which is child of a fieldset that gets cloned with jQuery.

If the cloned object has a value already set for the file input, it will keep it.

Thank you.

Here's a new approach using some of the tips from redsquare and Šime:

var $clone = $('#my-fieldset').clone(),
    $clonedFileInputs = $clone.find('input:file');

// this browser check is nasty, but I don't know how to feature-detect this...
if ($.browser.msie) {
    // avoid security error by replacing input, rather than setting value
    $clonedFileInputs.replaceWith(function() {
        return $(this).clone();
    });
} else {
    $clonedFileInputs.val('');
}

$clone.appendTo('#new-parent');
