Christopher, why do you think this is a bug in gnome-panel? I see that
gnome-panel is not even started in your screenshot.
I don't have the environment needed for reproducing this so can't look
at it, but patches are welcome.

Bug description:
== Impact ==
It was impossible to launch a gnome-session-based desktop on a system where
hardware accelerations is not available (such as old hardware, or when using a
remote desktop).
That looks like a quite popular use case — more than a hundred of
people marked this bug as affecting them.
== Test Case ==
The original bug description below contains a test case.
== Proposed Fix ==
The fix backports an upstream commit which adds --disable-acceleration-check
commandline option, and makes Upstart user session pass that flag to
gnome-session when the session is gnome-fallback (aka
gnome-flashback-metacity). Of course, that option can be used with other
sessions as well.
This was fixed in vivid in version 3.14.0-2ubuntu4.
== Regression Potential ==
The option was accepted upstream, and nobody complained so far. So the
regression potential should be low.
This bug will cause static grey or black screen instead of opening
remote session using Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting from
x2goclient, rdpclient(reminna/vinagre/mstsc), SSH, VNC, NOMACHINE and
etc.
== Original Description ==
1) lsb_release -rd
Description: Ubuntu 14.04 LTS
Release: 14.04
2) apt-cache policy gnome-session
gnome-session:
Installed: 3.9.90-0ubuntu12
Candidate: 3.9.90-0ubuntu12
Version table:
*** 3.9.90-0ubuntu12 0

3) What is expected to happen is when one installs xrdp on the host
and attempts to use remmina or vinagre on a Ubuntu 14.04 client to RDP
in, it works.
4) What happens instead is it shows a gray static screen as per attached
screenshot. This would appear an issue with gnome-session as per client log:
