I'm working on updating an iPhone application with a minor change in its default configuration. It's been awhile since I've built it last, though, and so I've upgraded Xcode to 4.2 and included iOS 5 support in the latest builds. When I go to test on the device, I get the following assertion error: 2011-11-02 20:57:18.869 RoseBandwidth[903:707] Tried to add item, got result: -25243 2011-11-02 20:5
