Whenever an app is installed, the usual routine is to run 'gtk-update-icon-cache' after installing all of the app's files. The side effect of that is that the .desktop file of the application is installed before the icon theme is updated. By the time GAppInfoMonitor emits the 'changed' signal, the icon theme is not yet updated, leading to StIcon use the fallback icon. Under some circumstances (e.g. on very slow spinning disks) the app icon is never actually loaded, and we see the fallback icon forever. Monitor the icon theme for changes when an app is installed. Try as many as 6 times before giving up on detecting an icon theme update. https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/661
