Bug#538108: /apps/nautilus/preferences/exit_with_last_window solves this problem

[Josh Triplett]

A comment <https://bugzilla.gnome.org/show_bug.cgi?id=571417#c31> on the
upstream bugzilla entry for this bug suggested a solution which should
work.  nautilus has a gconf entry
/apps/nautilus/preferences/exit_with_last_window, which determines
whether it will exit when it has no windows to display (including the
desktop).  exit_with_last_window=true by default.  Thus, with
show_desktop=false and exit_with_last_window=true, nautilus will exit
when launched by gnome-session, and gnome-session will then respawn it,
leading to the original bug.  However, with show_desktop=false and
exit_with_last_window=false, nautilus will continue running after
gnome-session launches it, avoiding both the original bug and the
current bug of not handling automounting anymore.

The comment suggested just setting
/apps/nautilus/preferences/exit_with_last_window=false as a mandatory
gconf setting.  This seems sensible.  It should have no effect with
show_desktop=true, as nautilus will already continue running in that
case.  With show_desktop=false, it should unbreak things.

Thus, could you please:

- Change gnome-session to include the file manager in the required
  components list again
- Remove the autostart file from nautilus that only starts nautilus if
  show_desktop=true
- Set /apps/nautilus/preferences/exit_with_last_window=false in
  mandatory gconf settings.
- Make the new versions of gnome-session and nautilus declare Breaks for
  older versions of each other, to ensure that they get upgraded
  together.  (Actually, the new nautilus could just declare Breaks for
  the specific versions of gnome-session that didn't launch nautilus,
  but you can't specify a range of versions and enumerating specific
  versions seems error-prone.)

Thanks,
