Turns out this also fails in noble, and wasn't seen before just because of ordering.
If we try to first reproduce the bug, and then update the package and
run again, it will work. Even though we get a crash at first when trying
to reproduce the bug, it did manage to create the policy file. Then when
we update to the package in proposed, and run the command again, the
policy file already exists, and we run through a different code path.
In noble, if you start fresh from the packages in noble proposed, this
bug is also not verified:
ubuntu@n-ad:~$ sudo samba-tool gpo manage motd set
{31B2F340-016D-11D2-945F-00C04FB984F9} "Welcome" -U Administrator%Passw0rd
WARNING: Using passwords on command line is insecure. Installing the
setproctitle python module will hide these from shortly after program start.

Package from proposed:
ubuntu@n-ad:~$ apt-cache policy samba
samba:
Installed: 2:4.19.5+dfsg-4ubuntu9.1

And it fails to create the policy from scratch:
ubuntu@n-ad:~$ sudo find /var/lib/samba/sysvol
/var/lib/samba/sysvol
/var/lib/samba/sysvol/example.internal
/var/lib/samba/sysvol/example.internal/Policies

In other words, the fix from this bug indeed fixes the update case, but
breaks the "create the policy from scratch/fresh" case.
