Well, -addPersistentStoreWithType:configuration:URL:options:error: is only being passed trivial parameters, except for the URL.  Log that URL and make sure that its parent directory exists.  Try passing options:0.  There's not very much you can screw up in there.

Always log the -userInfo if you'd like more details from an NSError.  There may be an underlying error (NSUnderlyingErrorKey).
