Conversion of Metadata Plist string Failed

In xCode, I'm building an iPhone app with Core Data, and with Objective C Exceptions checked for the Build, I'm receiving the following error in the Console:

Unresolved error Error Domain=NSCocoaErrorDomain Code=259 "The operation couldn’t be completed. (Cocoa error 259.)" UserInfo=0x611c2c0 {NSUnderlyingException=An error occurred converting the metadata plist: Conversion of string failed. The string is empty.}, { NSUnderlyingException = "An error occurred converting the metadata plist: Conversion of string failed. The string is empty."; }

This occurs when I try to run the app on the Simulator, and the app dies. When I try to run the app on my device (iPhone 3g), the program runs with the expected DB with full functionality, but when I close the app, the app will not relo开发者_JAVA百科ad on the device.

Any assistance will be appreciated. Thanks!!
