Failed to load module "appmenu-gtk-module"

[doubters]

FreeCAD from .appimage of new versions does not use the GTK-theme and at the start gives the following warning:
Gtk-Message: 15:14:33.586: Failed to load module "appmenu-gtk-module"
Gtk-Message: 15:14:33.586: Failed to load module "gail"
Gtk-Message: 15:14:33.586: Failed to load module "atk-bridge"

What could be the reason?

Confirmed on Ubuntu 18.04/GNOME.

Here's a more detailed output at launch. I also notice it takes a longer time to load the splash screen.

Code: Select all

$ ./FreeCAD_0.18_stable.AppImage /tmp/.mount_FreeCATTS59b

(FreeCAD:4004): GdkPixbuf-WARNING **: 10:44:37.132: Cannot open pixbuf loader module file '/home/travis/build/FreeCAD/FreeCAD-AppImage/conda/linux_stable/AppDir/usr/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache': No file or folder of this type

This likely means that your installation is broken.
Try running the command
  gdk-pixbuf-query-loaders > /home/travis/build/FreeCAD/FreeCAD-AppImage/conda/linux_stable/AppDir/usr/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache
to make things work again for the time being.

Even though the message indicates "your installation is broken", a quick test shows it to be functioning normally.

Maybe move this topic there entirely?
