It's an Old Port District Sewer Key, dunno why the sewer bit was omitted from the trivia.

I checked the one in the cellar, before you get the proper key from Havelock as well and it's the same there, and the key with the bugged name is nameless in my inventory, it just has the description "An old, rusty key."
