This code intermittently crashes:

[[[MKMapSnapshotter alloc] initWithOptions:mapSnapshotOptions] startWithCompletionHandler:^(MKMapSnapshot *snapshot, NSError *error) {
// completion Handler
}];


I did see this mostly on the Simulator so far because I haven't yet tested extensively on the device.
