+Subject: [PATCH] gnome-session: don't validate shell before using it
+
+Users sometimes set their shell to an invalid shell to prevent
+login from proceeding.
+
+GNOME on Wayland still allows login in these cases.
+
+This commit makes the behavior match expectations by skipping
+shell validity checks when deciding to run though a login shell.
