Comment 5 for bug 740844

This certainly is a tricky one..

This dialog is not a traditional application (it can't be launched directly) so it doesn't have an application name. The desktop file is /etc/xdg/autostart/polkit-gnome-authentication-agent-1.desktop - it's not in /usr/share/applications and shouldn't be used for naming information. Potentially polkit-gnome-authentication-agent-1 could launch different dialogs that have no relation to each other so there is no common name for polkit-gnome-authentication-agent-1 (or rather the current name is the most valid!)

I'd almost say this dialog shouldn't be shown at all in the launcher (it certainly shouldn't be able to be pinned), but you may need to switch to it (if you lose it under another window).

I'm going to dive into unity/bamf and see if they have a concept of a transient window that is not an application and see if they can detect this window as such.
