Huh, that file seems to have existed since I first set up the machine! Do you have any more information on this? For me it just contains the bytes `0x0:0x0`. How'd you know to try that and do you know how it worked at all?
Edit: The modification date is actually earlier than the added date -- it looks like the file was transferred by Migration Assistant from my previous machine! Not sure if that's important.
