Maybe your delegate object (‘self’ in your snippet) got dealloced? Have you 
tried turning on zombies?

There’s an easy-to-miss slider at the bottom of that view, that 
compresses/expands the backtrace. If you slide it all the way to the left(?) 
you’ll get the full backtrace. Don’t worry, you’re not the only person who 
missed this.
