Yeah, that is what I was expecting. The file did not exist. I created
it manually, yet it is still empty, even after rebooting the VM and
starting a session again.

Maybe Fedora 21 prevents output to this file by default? I will look into it.

I cannot launch gnome-terminal under the session because there is no
applications menu. However, I viewed /proc/2366/environ (PID 2365 is
gnome-settings-daemon) and this is set:

XDG_CURRENT_DESKTOP=GNOME

We're making progress! I removed that line from those 3 files. Now
when I launch a metacity session, I see the desktop wallpaper and
gnome-panel for a split second. Then I get the fail whale.

Still no .xsession-errors output though.
