When I pass glade-previewer v3.40.0 on a .glade file, on MYSYS2, like so
glade-previewer.exe --filename gui_file.glade
I get the error messages
GladeUI-Message: 18:11:25.933: 1 missing displayable value for GtkWidget::AtkObject::accessible-role
GladeUI-Message: 18:11:26.509: 5 missing displayable value for GtkCellRendererText::variant
GladeUI-Message: 18:11:26.622: Glade needs artwork; a default icon will be used for the following classes:

GladeInstantiableGtkBin needs an icon named 'widget-gtk-bin'
GtkFileChooserNative needs an icon named 'widget-gtk-filechoosernative'
GtkApplicationWindow needs an icon named 'widget-gtk-applicationwindow'
Launching glade itself also output a similar list of errors:
GladeUI-Message: 18:24:39.797: 1 missing displayable value for GtkWidget::AtkObject::accessible-role
GladeUI-Message: 18:24:40.594: 5 missing displayable value for GtkCellRendererText::variant

GladeUI-Message: 18:24:40.781: No DevHelp installed on your system, devhelp feature will be disabled.
What can do the fix this issue? I have tried upgrading all the packages on MSYS2 but that didn't work.
