I think it could be related to dual monitors. I have my laptop, and then my 24" Dell LCD that I plug into. On the Dell, when it's plugged in, I have a panel set to auto hide. When it's not plugged in, that panel doesn't show up on the laptop screen. This all happened randomly when I was not plugged into the monitor.
It's a bit scary how it can completely destroy your entire system. I couldn't connect to wireless easily because the wireless applet was gone, it killed X and froze everything, used up tonnes of CPU and memory. When I removed gnome-panel it basically rendered everything (including Nautilus) useless. Quite a major bug I would say, depending on how often it happens.
Appears to be a duplicate of bug 479826.
I fixed it by removing:
~/.gconf/ apps/panel/ general/ %gconf. xml
~/.gconf/ apps/panel/ toplevels/ panel_1
