dconf/dconf-use-g_settings_get_default_value.patch

From b25b57872daa036adbafeddb6aaf1236407bed1b Mon Sep 17 00:00:00 2001

Subject: [PATCH] Use g_settings_get_default_value() to retrieve default values

GSettings now has an API to retrieve a default value, and using it is
more reliable than parsing the schema ourselves.
