appearance: gfile warnings in terminal with newer glib versions

[lukefromdc]

Expected behaviour

no warnings in terminal when mate-appearance-properties is run from a terminal with no themes containing errors installed and with glib 2.76 or later installed

Actual behaviour

We get these three warnings:

(mate-appearance-properties:51586): GLib-GIO-CRITICAL **: 14:12:51.644: GFileInfo created without standard::type

(mate-appearance-properties:51586): GLib-GIO-CRITICAL **: 14:12:51.644: file ../gio/gfileinfo.c: line 1610 (g_file_info_get_file_type): should not be reached

(mate-appearance-properties:51586): GLib-GIO-CRITICAL **: 14:12:51.644: GFileInfo created without standard::type

(mate-appearance-properties:51586): GLib-GIO-CRITICAL **: 14:12:51.644: file ../gio/gfileinfo.c: line 1610 (g_file_info_get_file_type): should not be reached

Steps to reproduce the behaviour

Open mate-appearance-properties from terminal with glib 2.76 or later installed (I have confirmed 2.78 or later, when we had this in caja it was reported the warnings began with version 2.76)

MATE general version

1.28

Package version

locally compiled mate-control-center 1.29 from git master

Linux Distribution

Debian Unstable

Link to bugreport of your Distribution (requirement)

None as this is a locally compiled package. Should show up in every distro shipping glib 1.76 or later
