Missing icons in Gajim

[werner291]

Describe the bug

There are icons missing in Gajim.

The one appearing in the screenshot should be user-info-symbolic which is found in the gnome-icon-theme-symbolic package.

It was not in nixpkgs, but I believe I got a package compiling?

See: https://github.com/werner291/nixpkgs/tree/master/pkgs/data/icons/gnome-icon-theme-symbolic

Following the lead of the Arch Linux package of the same name, I added this env.GTK_UPDATE_ICON_CACHE = "${coreutils}/bin/true"; horrible hack to patch out the gtk-update-icon-cache because that pack doesn't have a theme index, whatever that might be.

Unfortunately, the icons don't appear in Gajim despite adding that to the build-inputs... I'm stuck at that point. (I suspect my "hack" broke it; I'm kinda just doing what Arch did)

Steps To Reproduce

Steps to reproduce the behavior:

1. Set up a NixOS system with Plasma 5 and Gajim.

Expected behavior

Icons show up.

I have a hypothesis...

In Arch, that hack works fine because the system is managed imperatively, and that icon database update will happen eventually. In Nix(OS), purity prevents that from working. Instead, we get that the icon database is not updated.

There's an option in gtk-update-icon-cache to not require a theme index; worth a shot maybe?

[werner291]

Changed it to env.GTK_UPDATE_ICON_CACHE = "${pkgs.gtk3}/bin/gtk-update-icon-cache --ignore-theme-index";

Icons do not show up either.

Not sure what to do at this point; I need someone who knows gtk better, I'm just throwing stuff at the wall to see what sticks.

FYI, I'm testing it with a flake based on the package in nixpkgs, does that matter?
