Application crash if productRequest returns an empty array of products #2

I'm getting this behavior on iOS 5: if the products request returns an empty array of products the application crashes.

I've tracked this down to CargoBay and in particular to one line of code in CargoBay.m, in the productsRequest:didReceiveResponse: method.

- (void)productsRequest:(SKProductsRequest *)request
     didReceiveResponse:(SKProductsResponse *)response
    if (_success) {
        _success(response.products, response.invalidProductIdentifiers);

     // commenting the line below remove the crash
    //[[self class] unregisterDelegate:self];

Hope it helps and it's not a problem I created in my specific situation.

…re blocks of delegate objects

Ah, I think I understand what's going on there. It would appear that there may be a race condition between the success block and the delegate being released. b94754b makes it so that the success block and the delegate unregistration occur on the same thread, synchronously. Let me know if that fixes your problem.
