~/.local/share/gnome-shell/application_state is a common problem.  It
contains some state that different versions of GNOME seem to be choking
on.  There are some other files like ~/.cache/gnome* that might affect
GNOME and prevent starting after upgrades.  It=E2=80=99s frustrating.

/var/lib/gdm is the home directory of the gdm account, and it too can
accumulate state.  In my opinion /var/lib/gdm should always be recreated
on every boot.
