I think the #012 is just rsyslog gobbledy gook. it's exit code 1 below
in your log.

so we create an auth cookie for the user in /tmp.  If /tmp is getting
replaced, the auth cookie won't be around anymore and clients won't be
allowed to talk to the server.

(and will probably exit 1).  I don't know if that's your problem
specifically, but it seems probable.

We should probably move the X auth cookies to /var/run/gdm

Do you have the ability to populate your /tmp during the login
process? if so, copying from the real /tmp that file would verify if
that's the problem or not (the location is stored in the XAUTHORITY
environment variable)
