Bug#747292: gdm3: Unable to login after last upgrade (version 3.8.4-7): fails to start a GNOME session

[Benjamin Menant]

Thank you for your time and efforts.

I tried adding this debug parameter into `/etc/pam.d/common-session`:
session	optional	pam_systemd.so debug=yes

Then, I flushed the auth.log and rebooted the computer (with v3.8.4-7).
Please see the attached file for results.


Also, when a Gnome session (through v.3.8.4-6) is running, I get these
directories:

# ls -l /run/user/
total 0
drwx------ 7 bmenant    bmenant    160 mai    8 14:14 1000
drwx------ 5 Debian-gdm Debian-gdm 120 mai    8 14:14 113


But, when gdm3 fails to open a Gnome session, I get this one from the
virtual console:

# ls -l /run/user/
total 0
drwx------ 2 bmenant bmenant 40 mai    8 14:29 1000


The `/run/user/` directory is 755 root:root.

The Debian-gdm user could fail to create its directory? Should I try to
create this directory from the VC before I try to open a Gnome session?

Thank you,
Benjamin.
