Further to this I copied this example: valadoc-org/examples/gtk+-3.0/Gtk.Viewport.vala at main · vala-lang/valadoc-org · GitHub
On Linux it worked fine and showed .png and .svg images.
On Windows it crashes:
$ viewport.exe ../hellogtk/images/icon.png
(viewport.exe:3048): Gtk-WARNING **: 11:25:49.875: Could not load a pixbuf from /org/gtk/libgtk/icons/16x16/status/image-missing.png.
This may indicate that pixbuf loaders or the mime database could not be found.

I also tried this example: valadoc-org/examples/gtk+-3.0/Gtk.IconView.vala at main · vala-lang/valadoc-org · GitHub
And again it works fine on Linux but crashes on Windows:
$ iconview.exe
(iconview.exe:2052): Gtk-WARNING **: 11:29:28.250: Could not find the icon 'help-about'. The 'hicolor' theme
was not found either, perhaps you need to install it.
You can get a copy from:

What am I missing or doing wrong?
