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.

$XDG_CACHE_HOME/gdm/session.log

Does this file exist?

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

What GDM version do you have? It should work with 3.12.1 or newer.

Are you sure that you start correct session? Maybe update gnome-jhbuild-session-flashback-metacity script to add extra environment variable (if there is some way to see it later), for example:
export MY_TEST_VARIABLE="test..."

Or just make that script to create empty file in your home dir.

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.

You need to find file where errors are logged to see why session crash.
