When the session manager enters the query end session phase, it temporarily adds all clients to the "query clients" list. This list is used to track the progression of clients quitting. If a client quits during the query end session phase instead of waiting until the end session phase, then it will get destroyed but not get removed from the query clients list. This commit removes it from the query clients list in this case. It does this by explicitly invoking the end session response handler (in effect, the client responded to the end session query by exiting). based on gnome-session commit: 8e6afcf1789c02692cf3b1ff3ee0a792d57e17a3 From: Ray Strode <[email protected]>
