+TL;DR: This is a bug caused by GTK Emacs 24 and recent glib\r
+(introduced somewhere between 2.33.12 and 2.36.1) when there's no\r
+D-BUS session daemon running. It was "fixed" in Emacs git two weeks\r
+ago, but you can temporarily work around the problem by running DBUS\r
+or by exporting GSETTINGS_BACKEND=memory.\r

+This is Emacs bug #14474:\r
+ http://lists.gnu.org/archive/html/bug-gnu-emacs/2013-05/msg00705.html\r
+ http://lists.gnu.org/archive/html/bug-gnu-emacs/2013-06/msg00002.html\r
+Paul Eggert found the same cause that David and I painstakingly\r
+tracked down over IRC:\r
+ http://lists.gnu.org/archive/html/bug-gnu-emacs/2013-05/msg00726.html\r
+This workaround was committed to Emacs git master on May 30th in 8dea8fe0:\r
+ http://lists.gnu.org/archive/html/bug-gnu-emacs/2013-05/msg00752.html\r
