Bug#941640: gnome-session: Gnome 3.34 fails to start showing grey screen "Oh no, something has gone wrong"

[Drew Parsons]

Package: gnome-session
Version: 3.34.0-2
Severity: grave
Justification: renders package unusable

With the Gnome upgrade from 3.30 to 3.34, a Gnome session now fails to
start.

gdm3 runs fine, the login screen is shown and I can proceed with
logging in.  But instead of logging in and starting a session, it
instead switches to a grey screen with the message

"Oh no, something has gone wrong. A problem has occurred and the
system can't recover. Please log out and try again." 

So Gnome 3.34 is currently unusable.

This is with Gnome x11, not wayland.
