+Subject: [PATCH] tests: Fix "new ID" type handling in argument_from_va_list
+ test
+
+New IDs are internally dealt with as objects, however this test
+expected to deal with 'n' as the uint32_t type that's just seen
+through the wire. We should give it an object instead, and
+expect an object from it.
