Nothing there looks obviously problematic to me...

Knowing what the rest of the system was doing at the same time is also 
necessary information, so please check the full Journal (using journalctl), 
not just the messages from gdm itself. For example there might be errors 
reported by gnome-shell or systemd-userdb or some other component at 
around the same time, and those are relevant too.

If that doesn't turn up anything obvious, then it might be necessary to 
raise the logging level by adding DEBUG_INVOCATION=1 to gdm.service or 
other relevant services (see a previous message to the bug), or booting 
with systemd.log_level=debug on the kernel command line, or both.

Unfortunately, because I can't see from the information provided which 
component is going wrong or in what way, I also can't say specifically 
what debugging steps will reveal the necessary information.
