TJ is right, I also confirmed this issue on a freshly installed 18.04.1
x86_64 Desktop VM last night. After enabling 'proposed' and installing
all pending updates, 'groups' in a terminal returned just the users
primary group. I then restored a snapshot taken right after the 18.04
installation (but
I've awk-ed a list of the packages Upgraded or Installed on July 28th on
the affected PC (previous upgrade was on July 8th). I've put a ? in
front of those that could be suspect. That list is short:

Tom tried those things in a VM last night and could reproduce it. On a
suggestion by Robbie Basak but the downgrade didn't solve it, which made
me suggest something in the configuration is being permanently changed.
I'm not going to downgrade the package because I am debugging it and
don't want
I've tried replicating your setup in a fresh bionic VM (ie. using tmux
as default shell which then launches bash) and I can't replicate this:
amurray@sec-bionic-amd64:~$ grep amurray /etc/passwd
amurray:x:1000:1000:Ubuntu,,,:/home/amurray:/usr/bin/tmux
amurray@sec-bionic-amd64:~$ echo $SHELL

It seems that /var/run/ConsoleKit directory and its database is only
created by console tty log-ins but not the GUI. There was no directory
after GUI Terminal shell started; only after switching to TTY1.
So it would seem this isn't the cause since PCs without ConsoleKit work
fine.

Looking at the diff between upstream 0.105 and Ubuntu's I happened to
notice the CKDB_PATH (ConsoleKit database path)
/var/run/ConsoleKit/database which seems to be consulted on some
occasions.
On the affected PC which was d-r-u-ed from 16.04 ConsoleKit 0.4.6-5 is
still installed and that
@TJ re comment:6 that fix is already in for both xenial and bionic as
far as I can see.

Title:
Regression due
Looking at the diff between Ubuntu and upstream I noticed Ubuntu 0.105
code isn't adapted for "systemd --user" as described in
https://bugs.freedesktop.org/show_bug.cgi?id=76358
and in the source for the function:
polkit_backend_session_monitor_is_session_active()
** Bug watch added:
I can't reproduce this myself but I am using the default shell (bash
provided by dash) and gnome-terminal. My understanding of the change to
policykit-1

The quirk is more nuanced than I reported above.
This reports groups correctly:
1. GUI login
2. Switch to TTY, login
3. "groups"
4. Switch to GUI
5. Launch Terminal
6. "groups"
This only reports the username:
1. GUI Login
2. Launch Terminal
3. "groups"
4. Switch to TTY, login
5. "groups"
I've discovered another quirk:
If my first log-in after booting is at the TTY console (not GUI) the
groups show up correctly there *and* in a terminal in the Xorg GUI
session afterwards.
But if I first log-in to the GUI then log-in to the TTY console both
show only the user group.

journalctl shows the problem with the auid and session values being
