Anyone know where I can report this issue? The link paulnj posted above is not working.
You need to have an account registered at Microsoft Connect for access to the WHS section. That's probably why the link isn't working for you.
So far, 28 people have reported that they are seeing this bug. Microsoft have ackowledged the problem and stated that
this alert is caused by an internal error "Object reference not set to an instance of an object", we are investigating the root cause, a quick workaround is you could "Ignore" this alert, do not "Delete".
