>Description:
Programs linked to gtk3+ seem to be missing a lot of icons. "gtk3-icon-browser" shows no icons or symbols at all, "meld" and "wireshark-gtk" show some icons, but also a lot of what looks like placeholders. A network capture of wireshark shows a symbol for a text entity instead of a double-headed arrow, and icons are missing for unfolding blocks in the structured packet view.

wireshark emits warnings like

Gtk-WARNING **: Error loading theme icon 'go-top' for stock: Icon 'go-top' not present in theme Adwaita

but gtk3-icon-browser shows no output to the console at all.

I was hoping for instructions (pkg_info -D) in gtk3+ to set a path, update a cache or similar, but there are none.
