With gdm3 3.8.4-8.1, after logging by ssh:

1. Before logging via gdm3:

         1        105 Debian-gdm       seat0           
         2       1000 vlefevre                         

2. Just after logging via gdm3:

         1        105 Debian-gdm       seat0           
         2       1000 vlefevre                         
         4       1000 vlefevre                         

3. Just after logging out from the desktop:

         2       1000 vlefevre                         
         4       1000 vlefevre

If I do these things, this makes the bug disappear.
