That this never worked reliably is simply not true. With the old GNOME
session manager (<=2.22), programs supporting the old XSMP protocol
(Firefox, OpenOffice, Gimp, and most programs using the GNOME libraries)
were indeed able to block session shutdown and ask you if you wanted to
save work (you can test it on Hardy). Also, for programs not supporting
XSMP, the session manager would ask you to terminate them by hand before
shutting down. The new GNOME session manager will just kill all running
programs without asking. This is very dangerous and will certainly
affect people who (maybe unconsciously) still rely on the old behavior.

Regarding gedit, it is one of the few programs that can block session
shutdown with the new session manager, and it seems to do this
incorrectly, by the way. With the old session manager, it used to work
well, as far as I remember.
