Top gnome-panel won't work on GNOME Flashback

[Ads20000]

Similar to this bug https://bugs.launchpad.net/ubuntu/+source/gnome-panel/+bug/1078679 but I can't use the script suggested to get the top panel to work at all. It just shades from dark on the left-hand side to light on the right-hand side (no application menu, system tray or anything).

This is fully updated Ubuntu 13.10 with GNOME and Xfce but logging into the 'GNOME Flashback (No Effects)' session.

I get this error in Terminal:

*** BUG ***

Reopen if this is still problem in newer Ubuntu versions.
