    libgimpwidgets: use g_printerr() instead of g_warning() for app icons.
    
    Unit testing consider warnings as criticals and doesn't like when it
    cannot find the installed application icons. To fix the `make check`,
    just print the missing icon information to stderr, but don't make it a
    GLib warning.
