[PyQt] QInAppStore.registerProduct() causes crash

[Dave Gradwell]

My code….

self.appStore = QtPurchasing.QInAppStore(self)
self.appStore.productRegistered.connect(self.on_productRegistered)
self.appStore.productUnknown.connect(self.on_productUnknown)
self.appStore.transactionReady.connect(self.on_transactionReady)
self.appStore.registerProduct(QtPurchasing.QInAppProduct.Consumable, "playall_standard_subscription”)

….crashes on the last line with the NSException as shown below.
Would be most grateful for any advice if I’m not using this correctly..

Thanks, Dave.
