I mean, this file is created by Core Data, by calling -saveToURL:... in the NSPersistentDocument subclass. So it's not really anything my app is doing. So unless the user somehow messed up the file, I suppose the file is in good order.

The file may be quite valid, but the parser is trying to decode an unsigned 64-bit integer into an actual variable. So maybe there's some issue with a really big (or somehow mangled) integer?
Try setting a breakpoint on strtoull_l and see what kind of arguments it is getting.
