Crash on iOS9 using [NSPsistentStoreCoordinator _coordinator_you_never_successfully_open_the_database_device_locked:]

Question

My app recently got these crash tests that only happen on iOS9

Fatal exception: NSInternalInconsistency exception
This NSPersistentStoreCoordinator does not have persistent storage (corrupted file). It cannot perform a save operation.

Last call from report

-[NSPersistentStoreCoordinator _coordinator_you_never_successfully_opened_the_database_device_locked:]

and this is how NSPsistentStoreCoordinator is created

 - (NSPersistentStoreCoordinator *)persistentStoreCoordinator{
    if (_persistentStoreCoordinator != nil) {
        return _persistentStoreCoordinator;
    }

    AppDelegate *delegate = (AppDelegate *)[UIApplication sharedApplication].delegate;

    NSURL *storeURL = [[delegate applicationDocumentsDirectory] URLByAppendingPathComponent:@"database.sqlite"];

    _persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:self.managedObjectModel];

    NSError* error = nil;

    if (![_persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType
                                                   configuration:nil
                                                             URL:storeURL
                                                         options:@{NSMigratePersistentStoresAutomaticallyOption:@YES, NSInferMappingModelAutomaticallyOption:@YES} error:&error])
    {
        NSLog(@"Error adding persistent store. %@, %@", error, error.userInfo);
        return nil;
    }

    return _persistentStoreCoordinator;
}

Does anyone know what could cause these accidents?
