I've had some of those crashes recently too. In my case I tracked it down to some bad code I'd written in a KVO method which was throwing an exception when it was getting called for an update. Instead of seeing the error (invalid selector I think it was) the app just crashed, when put under the debugger I too ended up at _unwind_resume.
Adding a try/catch around some main bits of the app found the real issue for me.
