We are adding a custom field to a blog post in order to hold an image url. Since we are in 4.1 we tried using the newly updated "ImageField" interface widget (which still has a ton of issues). When we add the "Blog Posts" control to a page, it works by default. However, when we try to select a single blog or single post, on save we get an "Object reference not set" message in a popup. From then on, the module shows "Object reference not set" in the preview box and when clicking the edit button again we get the ASP.NET error page within the popup. Below is the error message from the popup:
Server Error in '/' Application.
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.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1
We did some additional testing and found out that it only happens with the blog module and doesn't have anything to do with the "ImageField" widget. All that you need to have is a custom field on the blog posts and it fails.

Just to mention, or to validate, that I ran into the same problem. I ended up having to manually code my individual post.
