Finally did some debugging.
I've tried removing xserver-gl (which removed
/etc/X11/Xsession.d/98xserver-xgl_start-server) - no change.
I've tried commenting out gpg-agent (no change).
My .xsession-errors:
(process:17990): Gtk-WARNING **: This process is currently running setuid or
setgid.
This is not a supported use of GTK+. You must create a helper
program instead. For further details, see:

(process:17994): Gtk-WARNING **: This process is currently running setuid or

/etc/gdm/Xsession: Beginning session setup...
And the all inportant strace I'll attach :-) (strace -e trace=process -f -p
(2nd gdm process))
The exec's are both referring to "/usr/bin/gdmflexiserver" which isn't itself
setuid
