Bug#726535: gdm3: Multiple sessions are kept around

[Julian Andres Klode]

Package: gdm3
Version: 3.8.4-2
Severity: normal

On my system, two GDM sessions  are kept around, after
I logged in into a few other accounts (there are also
two user sessions in loginctl, but session 2 there only
has a single PulseAudio instance that did not migrate
correctly to session 30, and the session does not
exist in CK, so don't let that confuse you).

jak at jak-x230:~$ loginctl 
   SESSION        UID USER             SEAT            
         2       1000 jak              seat0           
        30       1000 jak              seat0           
        39        110 Debian-gdm       seat0           
        40        110 Debian-gdm       seat0           

4 sessions listed.
