As of the March 20, 2010, update, the nautilus panels, desktop icons will not load on startup. I've tried to run nautilus manually (somehow Docky is still loading) to no avail. This message pops up in the terminal:

(nautilus:2209): EggSMClient-WARNING **: Could not load desktop file '/usr/share/applications/nautilus.desktop': Key file does not start with a group
Segmentation fault (core dumped)
