UIManagedDocument CompletionHandler not executed i

I hope someone has some thoughts on this one...

I have a project that uses UIManagedDocument. The first thing I do in the appDelegate is open the document. Everything has been going fine until suddenly (nothing was changed in the code) the -openWithCompletionHandler: stopped executing the handler code. The app works just fine on the device, but not in the simulator. As a lark I tried running the app under the iOS 5.0 and 6.0 simulators and everything works as expected!?!

I have reinstalled xcode 4.5 and the behavior stays the same. I deinstalled by trashing the xcode app in the applications folder. I also deleted all the iPhone simulator files in the ~/Library/Application Support/iPhone Simulator/ directory.

Anyone have any thoughts?
