Problem Description: The tray icon for qbittorrent does not appear. It is a blank space between the other icons. This issue seemed to be solved by manually running, as root, "update-desktop-database /usr/share/applications/" My system: XFCE, AMD64, systemd Custom Profile - Combo Of: gentoo:targets/systemd gentoo:default/linux/amd64/17.1/desktop From Install Phase Of Emerge: >>> Installing (1 of 1) net-p2p/qbittorrent-4.2.1::gentoo /var/tmp/portage/._unmerge_/net-p2p/qbittorrent-4.2.1/temp/environment: line 709: gnome2_icon_cache_update: command not found * Updating .desktop files database ...

I also ran, as root, "gtk-update-icon-cache". The ebuild should have already run those things. It is currently unclear if my manual intervention did infact solve the problem or if there is something else going on.
It is because gnome2-utils.eclass silently does not provide gnome2_icon_cache_update in EAPI-7...
Fixed.
