Bug#604043: gnome-session: when choosing GNOME/Openbox as my session, both metacity and openbox get started

[Jim Paris]

Package: gnome-session
Version: 2.30.2-3
Severity: normal

Hi,

I log in via GDM by selecting the "GNOME/Openbox" session.  After a
dist-upgrade (upgrading gnome-session from 2.22.3-2 to 2.30.2-3), 
I now get metacity started as a window manager, and openbox started
shortly after.  Then openbox and gnome-settings-daemon seem to spawn
in a tight loop, taking up all CPU with various kdeinit (?!) processes.

If I run "killall metacity ; sleep 1 ; killall metacity", everything
goes back to normal and openbox loads as expected.

I'll attach the first 100 lines of my ~/.xsession-errors.

I changed the /desktop/gnome/session/required_components/windowmanager 
gconf key from "gnome-wm" to "openbox", and now it works properly,
but I don't think that should be necessary.

My /etc/alternatives/x-window-manager link points to /usr/bin/openbox.

I don't know if this is really a gnome-session or openbox-session
problem, but since gnome-session was the one that spawned two
windowmanagers, I figured I'd start here.
