Jonas, I don't understand why you reopened this bug. The NMU was done for Debian 12 and Testing. There is a new major release in Unstable that doesn't suffer from the bug the NMU was designed to fix. (It has a different bug but there is already an RC bug for it.)
I don't see any action Maintainers can do here…except close this bug. Admittedly, the new release in Unstable happened today so maybe the situation has changed after the bug was reopened. Thank you, Jeremy Bícha
