Binary package hint: gnome-panel
In the Natty i386 24-Mar-2011 daily-live CD environment (natty-desktop-i386.iso, md5sum 2337d865ac77319c082fd4753789c90b) with gnome-panel 1:2.32.1-0ubuntu6, when I click Try Ubuntu and the desktop comes up, neither the top nor the bottom panels appear. However, gnome-panel is running:
ubuntu@ubuntu:~$ ps ax | grep -v grep | grep panel
4435 ? Ss 0:00 /bin/sh -c gnome-panel
4437 ? Sl 0:02 gnome-panel
4471 ? Sl 0:00 /usr/lib/gnome-panel/wnck-applet
4478 ? Sl 0:00 /usr/lib/gnome-panel/notification-area-applet
Here's a screenshot showing the absence of panels (this screenshot shows a different bug being reported, which turned not to likely be related to this problem):
https://bugs.launchpad.net/ubuntu/+source/gconf/+bug/741458/+attachment/1935316/+files/desktop-without-panels.png
Windows are able to occupy the parts of the screen where the top and bottom panels would be. But when I kill gnome-panel with SIGTERM, windows are automatically moved upward in the screen. Killing gnome-panel does not cause it to be automatically relaunched. When I relaunch gnome-panel manually from the Terminal, both the top and bottom panels appear and are functional, but I get:
ubuntu@ubuntu:~$ gnome-panel
** (gnome-panel:4967): WARNING **: Failed to load applet NotificationAreaAppletFactory::NotificationArea:
GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface `org.gnome.panel.applet.AppletFactory' on object at path /org/gnome/panel/applet/NotificationAreaAppletFactory
And the corresponding error message dialog box appears on the screen. I know there is a bug (or bugs) that cause these sorts of errors; perhaps this error is not actually related to whatever problem is preventing gnome-panel from displaying.
This also occurred with the 23-Mar-2011 daily-live. I had not used the last few daily-lives before that, so I don't know at what point this bug was introduced.
I've attached a copy of .xsession-errors, from after I relaunched gnome-panel.

This is in a classic desktop (not Unity), since the machine running the live CD system is a VMware Workstation 7.1.3 build-324285 virtual machine without graphics acceleration enabled. (The host machine, in case that's relevant, runs Maverick amd64.)
