What is the 'pam-panel-icon' window?

view story

http://unix.stackexchange.com – After starting GNOME desktop, a window titled 'pam-panel-icon' appears, initially displayed in the upper-left of the desktop sized as small as possible. It can be re-sized, minimized, or maximized, but if it is closed it immediately reappears. There is an old bug report seemingly describing the same behavior with a status of 'CLOSED NOTABUG' filed here: https://bugzilla.redhat.com/show_bug.cgi?id=233933. What is the purpose of this window? How do I make it go away? (HowTos)
