+Subject: Check the settings path when loading preferences
+ The gnome_bg_load_from_preferences public function is called
+ to load and validate gsettings key values. Patch
+ git_revert_draw_background restores the key draw_background
+ only for the org.gnome.desktop.background schema.  This patch
+ ensures that when this public function is called, the restored key is
+ explicitly obtained from the background schema. This prevents
+ segmentation faults when the public function is called, for example,
+ with the GNOME3 screensaver schema.
