I encountered the same issue on my older Sony Vaio VGNFS195VP after a fresh installation of Natty Narwhal. For everything I want do on the Desktop, nautilus pushes the CPU of my laptop to 100% for about 3-5 seconds and stalls the whole system (see picture with system monitor). Only after these 3-5 seconds of "nautilus thinking" I can perform the task I wanted to to, be it simply renaming an icon, drawing a selection over some icons, or even moving a single icon around. This is very painfull! I am not able to help any further, but maybe it is just a matter of my old laptops low ressources (Intel Pentium M with 1.60 Mhz, 1 GB RAM, Nvidia GeForce 6200 Go with 128 MB RAM). Or has it something to do with the transition from Gnome 2 to Gnome 3? By the way, this issue happens either with Unity, Unity-2D or the classic environment and with either the Nvidia driver, the Nouveau 3D accelleration or nothing of them installed. I hope you can fix this issue for the next release ...
