I'm writing my first iPhone app, so I haven't gotten around to figuring out much in the way of debugging. Essentially my app displays an image and when touched plays a short sound. When compiling and building the project in XCode, everything builds successfully, but when the app is run in the iPhone simulator, it crashes.

I get the following error:

Application Specific Information:
iPhone Simulator 1.0 (70), iPhone OS 2.0 (5A331)
*** Terminating app due to uncaught exception 'NSUnknownKeyException', 
reason: '[<UIView 0x34efd0> setValue:forUndefinedKey:]: this class is not key value 
coding-compliant for the key kramerImage.'

kramerImage here is the image I'm using for the background.

I'm not sure what NSUnknownKeyException means or why the class is not key value coding-compliant for the key.
