Yes, that should be safe - the only domain / network object set in an error condition is one that is passed in via the original caller. So there should still be a reference count held on these objects further up the call stack and thus this code won't actually free them immediately, merely decrement the ref count. Can probably confirm this by turning on debug mode and checking the messages.
