When submitting an attachment, the next page is blank.

this is because the client doesn't say that it will accept javascript as a response.

Here is a work around

$(function() {

$.ajaxSetup({
'beforeSend': function(xhr) {
xhr.setRequestHeader("Accept", "text/javascript");
}
});

});

See if this issue goes away in Rails 3.1
