The crash is happening because in  funtion when The cachedImage decoding fails it still calls didFinishLoading
DocumentLoader::substituteResourceDeliveryTimerFired(WebCo

loader->didReceiveData(data->data(), data->size(), data->size(), DataPayloadWholeResource)--> can DecodeFail  
......
.......
loader->didFinishLoading(0); ---> calling this without checking for errorOccured()
}
