Bug#898147: gdm3: fails to start: ("Oops! A problem has occured!" screen)

Package: gdm3

Version: 3.28.1-1


--- Please enter the report below this line. ---

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate
***

        * What led up to the situation?

Installed GDM3.


        * What exactly did you do (or not do) that was effective (or
          ineffective)?

For now, just started to do some debugging... (I copy the output of
relevant systemd-related commands below.)

  From what I could see in the log (journalctl), it seems to have something
to do with GLibC...
However, I don't know to which glibc/gdm3 version to downgrade to, as I
have all packages from testing...

        * What was the outcome of this action?

When booting, GDM3 fails to start. It gives me the "Oops! A problem has
occured!" screen.
The system boots OK with both SDDM and LightDM.

        * What outcome did you expect instead?

GDM to start correctly.


        * Additional logs:

Here is the output of relevant systemd-related commands ("systemctl" and
"journalctl").
