I have a user in the wild generating crashes in Crashlytics that are occurring within the EEE framework. It happens in a couple of different flavors, but they're all basically like this:

What could be the root cause of this error? Is it a corrupt contact of some sort? Is there a process within the framework for flagging such contacts and avoiding them? I don't care if a few contacts don't get parsed or included - I just don't want the app to crash.
