How to reproduce

1. Create a badge, set a quality
2. Edit the badge, edit one or more options, but not the quality, and save
3. The history has now an obvious entry, something like: Luke updated the quality for this badge from "Uncommon" to "Uncommon".

I tested this with every option, this entry get's always created. This issue was not always present, see https://secure.phabricator.com/badges/view/2/#75 for example.
