Systemd updated from 237.64-1 to 238.76-1 and loginctl is now broken

Hello,

I have a problem updating systemd from version 237 to 238 (I encountered this problem the day Arch shipped 238 but I haven't had the time to debug it then), and it seems that the problem is coming from pam_systemd calling loginctl.

So once systemd has been updated, logging in will produce no session:

$ loginctl 
   SESSION        UID USER             SEAT             TTY             

0 sessions listed.

I see this in the journal (with pam_systemd debug active)
