That makes sense, except that the consolekit stuff appears to not be
propagated. Perhaps the true cause of these problems is a bug in
consolekit? Although from my readings on consolekit, it is not intended
to propagate sessions across changing ttys (as in text login tty ->
xinit tty).

There are other ways (* see below), but that is by far the easiest and
cleanest at the moment.

Reproducing it appears to be straight-forward:
0) remove .xsession, .xinitrc, and other similar X customization files
1) install libpam-ck-connector
2) kill all /sbin/login processes (so login reloads the pam stack)
3) log out and log back in
4) run polkit-auth (all necessary permissions will be present)
5) run startxfce4
6) run polkit-auth from a terminal (most permissions are now missing)
Alternatively:
0) - 4) same as above
5) ensure /etc/alternatives/x-session-manager links to xfce4-session
6) run startx
7) run polkit-auth from a terminal, and most permissions are missing
I will put this information in the thunar bug as well.
* Other ways I have found that work:
- symlink /etc/alternatives/x-session-manager to /usr/bin/startxfce4
(but this defeats the true purpose of alternatives in this case)
- custom $HOME/.config/xfce4/.xinitrc or $HOME/.xinitrc with
ck-launch-session in an appropriate place (but this prevents the user
from benefitting from future improvements to the Debian X startup
process in /etc)
I'm sure there are other ways, but they will probably all be messy and
non-Debian-standard.
I did have another thought - if there is stuff that startxfce4 does that
xfce4 requires, maybe that stuff, or a call to startxfce4 itself, should
be integrated somehow into /etc/X11/Xsession.d/*? Something like what is
done in /etc/X11/Xsession.d/55gnome-session_gnomerc? Then the
alternative just needs to be pointed to xfce4-session, and no .xsession
in the home dir is required - seamless for the user.
