All packages current as of dapper / march 17th 2006
I log in as normal; the panel shows up, sometimes just a grey box, sometimes a box with the ubuntu logo in the corner (my root menu), sometimes as that and the message that there was an error adding the window list applet, do I want to remove it from the config; then it hangs. And window movement covering the panel or the error message causes them to become default grey (ie, the redrawing has stopped)
Backtrace from within an X server + xterm session, as I can't do anything in gnome without the panel.
