I will try the version from git master.

1. It looks like this is a bug. I will submit a patch.
https://git.gnome.org/browse/gnome-flashback/tree/data/gnome-flashback-metacity.desktop.in.in
https://git.gnome.org/browse/gnome-flashback/tree/data/gnome-flashback-compiz.desktop.in.in
2. I edited the .xsession file on my system and it did not fix the
issue with the local session. (I made sure to restart GDM).
3. It did fix compatibility with the simple project I have been
working on all day (xsession-chooser-pygtk), which I was using under
TigerVNC. My project uses the .xsession file:
https://github.com/mikedep333/xsession-chooser-pygtk
4. When I had that wrong logic in my ~/.Xclients file for TigerVNC,
bash tried to execute "GNOME", but it left the environment variable
set to "GNOME-Flashback". So some autostart apps were not starting up
correctly under TigerVNC., but now they are under TigerVNC.
