Looks good to me.  I think I would prefer three options:

1) Crash / go to debugger on uncaught exception.
2) NSLog the exception and continue.
3) Pop up a modal dialog asking the user to choose between the two  
behaviours.

Option 3 would be useful for debugging.  I don't like the current  
behaviour, since the dialog is non-modal and the app appears to  
continue for a little while behind it then die, and neither button has  
ever actually done anything when I've clicked on it...
