Good. I hope to find it.

These two lines apear just after locking the system (gdm started with
[debug] Enable=true). Nothing else is shown when I try to enter the
password to unlock the screen:

Sorry, that was my error when reporting the bug. Version 3.38.0-2 DOES
WORK, but upgrading to the current testing version (3.38-1.2) DOES NOT
WORK.

You are right. It could be some change in mobian that is incompatible
with the upgrade of gir1.2-mutter-7 and libmutter-7-0. If you think
that's the case, I'll report the bug to Mobian developers, as you
suggest.
