Does this ring a bell?

Melvin, the same change went as well in other stable series, 6.6.88,
6.12.25, 6.14.4, can you test e.g. 6.12.25-1 in Debian as well from
unstable to see if the regression is there as well?

Might you be able to bisect the upstream stable series between 6.1.133
to 6.1.135 to really confirm the mentioned commit is the one breaking?

Regards,
Salvatore
