I don't think this is due to anything you did wrong; most likely, there was simply a single-bit memory or disk error that broke the checksum of your conffile.

Not easily, and for that I reassign the bug to dpkg rather than just closing it outright. However, this is a low priority issue since it's unlikely to affect many people who don't have failing hardware.
