I'd be interested to know how John is going to fix this problem. I myself have used the performSelector:withObject:afterDelay:0.0 solution in situations like this
I think the problem really only happens with the NSKeyValueObservingOptionInitial option, which causes KVO to make a bunch of calls to user code (with potentially lots of side effects) directly inside -addObserver:etc:etc:. So the afterDelay: idea wouldn't really help, since in both cases -addObserver: is going to be catching and rethrowing exceptions. (One of our guys noticed that the crash report had objc_exception_rethrow, instead of objc_exception_throw, which I never noticed until he pointed it out.)
The solution was to find and fix the root cause of the exception, but hunting down the source of the exception is the hard part. The above knowledge, however, should help in the future. We were absolutely down the wrong path in suspecting self and -init.
