It works fine on Chrome and Firefox.

on my first dialog I have a link button and this fires a standard js function

function AddContributor(id) {

    var currentUrl = window.location.href;
    currentUrl = currentUrl.substring(0, currentUrl.lastIndexOf('/') + 1);

    var options = SP.UI.$create_DialogOptions();
    options.url = currentUrl + "/SecondPage.aspx?id=" + id;
    options.title = "Add";
    options.width = 700;
    options.height = 600;
    options.dialogReturnValueCallback = AddContributorCallback;

    SP.UI.ModalDialog.showModalDialog(options);
}

function AddContributorCallback(dialogResult, returnValue) {
    if (dialogResult == SP.UI.DialogResult.OK) {
        SP.UI.Notify.addNotification('xxx');
        SP.UI.ModalDialog.RefreshPage(dialogResult);
    }
    if (dialogResult == SP.UI.DialogResult.cancel) {
         SP.UI.Notify.addNotification('xxx.');
    }
}

first looking at your code you have taken the if statment out of the try catch block where it should be inside the try block so you can catch the error when debugging.

The next issue is that it returning null, probably because its out of the try catch block and/or the object doesnt exist in that time when your clicking on it so your calling somthing (object) that hasnt been created yet or has been desposed off causing it to be null.

as i cant properly see a part of the code that could be causing it I can only speculate that you have click on the first modal which runs fine but then on the second one it throws the error as it doesnt exist what your calling or the code that its failing on is not in the right place!

hope this helps :)
