As I understand it, a dangling pointer results when I fail to take ownership of something that I should. What kinds of objects are candidates for retaining in this way? Is there anything relating to settings bundles that are suspect in this area? My best clue is that the crash happens the instant I tap the Settings App icon after the app enters the background.

The rule of thumb is that any object reference you got that wasn't received through an alloc/init or copy, you have to specifically retain if you want to keep the reference around.
