Notification History Request Date Search Error: Object reference not set to an instance of an object.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a new NotificationHistoryRequest:

GCheckout.OrderProcessing.NotificationHistoryRequest req = new
GCheckout.OrderProcessing.NotificationHistoryRequest(
    GCheckoutConfigurationHelper.MerchantID.ToString(),
    GCheckoutConfigurationHelper.MerchantKey,
    GCheckoutConfigurationHelper.Environment.ToString(),                   
    DateTime.Now.Subtract(new TimeSpan(30, 0,0,0)), 
    DateTime.Now
);

2. Send the NotificationHistoryRequest request:
GCheckout.OrderProcessing.NotificationHistoryResponse resp =
(GCheckout.OrderProcessing.NotificationHistoryResponse)req.Send();

What is the expected output? What do you see instead?

I am expecting a successful response and not an error. The 
NotificationHistoryResponse should contain a list of NotificationResponses
filtered by a start time and end time. The error I receive is as follows:

Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information
about the error and where it originated in the code.

Source Error: GCheckout.OrderProcessing.NotificationHistoryResponse resp =
(GCheckout.OrderProcessing.NotificationHistoryResponse)req.Send();

GCheckout.GCheckoutRequest.Send() +56

Try changing your endtime to at least 5 minutes in the past. You can check your
sandbox's Integration Console to get more detailed errors to your request.

Thanks, that is brilliant. Changing the endtime to 5 minutes in the past works. 
I can
now list the notification history.

I had checked the Integration Console before but I did not see any errors. Today
though the errors are showing with the message 'The times you specify must be at
least 5 minutes in the past'. 

Thanks for your help!

I added a fix in the latest version that should account for this condition.
It will be in v2.5.0.1
