+Subject: [PATCH] settings: fall back to settings.ini gtk theme if requested
+ theme fails
+
+If a gtk3 application is run in gnome2 and the settings daemon uses
+xsettings to request a gtk2 theme with no gtk3 version (which is the
+case by default), then instead of failing to load any theme, we should
+attempt to fall back to the theme specified in settings.ini files.
