I have an application that uses the Parse.com iOS SDK with local data storage ( [PFObject pin]).
Some of our users get this crash in production, as we see in the Crashlytics report for flow failure:

My assumption is that this happens when the database schema changes between application updates, but this is an almost pure assumption.
I am looking to find out if anyone knows about preventing this failure by catching an exception, or setting some SDK configuration parameters.
Our pinned objects are only for collecting data and user sessions and can be safely deleted if necessary.
