[gdk-pixbuf/ebassi/for-master: 1/3] Use g_filename_display_name() with files inside GError messages

[Emmanuele Bassi <ebassi src gnome org>]

commit 192e948c54a032d0797254c9287339a91b7fb0a0
Author: Emmanuele Bassi <ebassi gnome org>
Date:   Fri Apr 16 18:30:37 2021 +0100

    Use g_filename_display_name() with files inside GError messages
    
    The path of a file may contain non-Unicode glyphs, as file names have
    their own encoding.
