Comment 4 for bug 1513554

Works for me. I was unable to select any stock cancel reasons in the interface, trying to delete them via the database threw the expected error message, and the pgtap test ran successfully.

I added a commit with some documentation because I was concerned people might not understand why they couldn't select a checkbox in the interface. If you have no custom cancel reasons, it's difficult to tell that they're grayed out.

Signoff branch with the additional doc commit is available at:
