Bug#871032: gdm3: Long delay during shutdown from Gnome session "A stop job is running..."

[Gabor Kertesz]

Package: gdm3
Version: 3.22.3-3
Severity: normal

Dear Maintainer,

After powering off from my Gnome session usually there is a 90 sec delay with
the following message on the screen:
"A stop jobb is running for Session c2 of user Debian-gdm". There is no further
detail and no way to skip waiting.

Curiously I never saw this happen when I log off and then power off from the
login screen.
