Pity, that would have been my suggestion, as this usually fixes any
problems with GDM and gnome-shell for me after upgrades.

The question here is: is it a failure of GDM or gnome-shell?  The exact
point where GDM starts gnome-shell is hard to pin-point, of course, but
the logs (even those on TTY1, Ctrl-Alt-F1) might tell you something
about whether it is gnome-shell that is crashing or if it doesn=E2=80=99t e=

get that far.

Other problems may include a failure to start some user services via
dbus.

This is tricky and frustrating.  I hope someone here will come up with
an idea to make this more robust.
