Please post your code, it's the only real way to investigate the issue
(especially since you're using operations/multithreading, where the
errors can be extremely subtle).

You were right. Copy-pasting the relevant code revealed that doing a [delegate performSelectorOnMainThread] while the main thread is blocked waiting for the last operation to finish is not a good idea ;-)

Thanks,
