As the content of input structures is beyond your control (even when QC acts
according to your expectations, users are sure to mess it up) you should use
NSObject's introspection methods (isKindOfClass: etc) to examine structure
inputs before calling any methods on them.
I can't however answer your question as to why... but you can NSLog(@"%@",
[self.inputMessage description]); to examine what you're receiving
