+Subject: [PATCH] tests: fix test_gvalue_flat_array_in_item_marshal_failure for
+ Python 3.12
+
+See https://gitlab.gnome.org/GNOME/pygobject/-/issues/582
+
+_PyGI_ERROR_PREFIX() no longer works with 3.12 since we only get normalized
+exceptions in there and can't add a prefix like "Item X: " to the message.
+
+Until we figure out how to add this back for 3.12, align the tests with the
+new behaviour (the new exception notes API would be an option, see the
+linked issue)
