The first idea that comes to mind is that it went through many different people in different services. It's not that any individual was retarded beyond all hope, it's that it got passed around between many people, for different distances. One of the intermediaries has a problem with Outlook so they can't open e-mails at the moment. Therefore, the most straightforward way to show them something is to print it out. Then they forward it to someone else who can't be arsed to walk to the other building 2 miles away so they scan it and send it. If the original user wasn't aware that the text box was copyable, he immediately thought of making a screenshot. Or maybe he had prepared his screen so that it was a fullscreen screenshot with useful context, but someone in the middle decided to do you a service a cropped the image. I can totally imagine that error report going through a Rube-Goldberg-worthy adventure into your inbox. Tell me, how many people were involved in the routing of that error report?
