Ubuntu Version: 18.04
gnome-session-common Version: 3.28.1-0ubuntu1

What's expected to happen: $XDG_CONFIG_DIRS is the same on every login
What happens instead: $XDG_CONFIG_DIRS gets expanded on every login

It seems that $XDG_CONFIG_DIRS gets expanded by two entries on every login.

On first login it looks like this:

/etc/xdg/xdg-ubuntu:/etc/xdg/xdg-ubuntu:/etc/xdg

On second login it gets expanded by the same two entries in front:

/etc/xdg/xdg-ubuntu:/etc/xdg/xdg-ubuntu:/etc/xdg/xdg-ubuntu:/etc/xdg/xdg-ubuntu:/etc/xdg

On third login, two more entries get added:

/etc/xdg/xdg-ubuntu:/etc/xdg/xdg-ubuntu:/etc/xdg/xdg-ubuntu:/etc/xdg/xdg-ubuntu:/etc/xdg/xdg-ubuntu:/etc/xdg/xdg-ubuntu:/etc/xdg

At this point Visual Studio Code, which lead me to this, no longer starts and just throw a Segementation fault/Core Dump.

I suspect this behaviour is triggered by /etc/profile.d/xdg_dirs_desktop_session.sh adding more stuff to XDG_CONFIG_DIRS on every login.
