+Description: Choose default session in /etc/gdm/custom.conf using DBus
+ Add /usr/lib/gdm-set-default-session to properly define default session:

+Subject: [PATCH] common: don't tank on criticals
+
+Tiny (or not so tiny) bugs in components below GDM in the stack
+can lead to critical warnings.
+
+In development releases, GDM by default will crash when encountering
+a critical warning.
+
+Losing the login screen is a big deal.  We shouldn't automatically subject
+our users to "can't log in" in order to highlight bugs in development
+releases.
+
+This commit removes fatal criticals by default.
