Bug#850291: gdm3: does not work without gnome-session

[Pascal Liehne]

Package: gdm3
Version: 3.30.2-3
Followup-For: Bug #850291

Hi,

It looks like the bug is back. After install of gdm3 and gnome-terminal
in one command and login I get only the background image.

HowTo reproduce:
- Install Debian 10 RC1 via Netinstaller without additional software
- run: apt-get install gdm3 gnome-terminal
- reboot, so gdm3 ist started
- login
- you will see only the background image.

Workarounds:
a) Install gdm3 and gnome-terminal in two commands:
- apt-get install gdm3
- apt-get install gnome-terminal
On this way gnome-session{,-common} will be installed automaticaly

b) Install gnome-session manualy

It didn't helped to
- switch to sid and run dist-upgrade
- upgrade gmd3 from experimental
