Hi Michal， is this the duplicate bug as bug 2121141?
Comment 3 Michal Privoznik 2022-08-25 08:52:20 UTC 
Yes, I believe so. Huh, I haven't realized this bug exists, sorry. I could have backported the patch earlier.

Never mind, I will close this bug as duplicate. Thank you for confirmation.
And I have tested the scratch build, there is no error messages any more like in comment 0.
