I'm working on a Mac app that's in the Mac App Store. I've received a number of crash reports caused when adding a product to the _products dictionary. Unfortunately I've not been able to recreate the crash. I can see three possibility that could cause this part of the code to crash:
_products does not exist.
product.productIdentifier is nil.
product is nil.
But honestly I don't see how any of the three would ever happen, and I'm at a loss as to why -[RMStore addProduct:] is crashing from time to time.
I've included the latest crash report below. Any suggestions on might be happenings and how to prevent the crasher is greatly appreciated.
Thanks,
