When gnome starts, usually nautilus starts to manage the desktop. I didn't like this so I turned it off in gconf, Nautilus shouldn't start (and it doesn't with older version), but it does on gnome startup, what is more it crashes and takes 100% cpu until killed. This happens with 2.20.0-r1 nautilus version. If it is significant, then I'm using comiz-fusion and xfdesktop. Reproducible: Always
Some recent gnome updates fixed this issue.
