Bug Description

Those icons are svg which have a reference to the background image, it leads nautilus to read the image for each variant of this icon it leads on session start and induce a several seconds delay to the desktop start

nautilus seems to load the background image 9 times on start (it's probably doing it for each variant) and it creates over 3 seconds of cpu pick for nautilus on an atom cpu

This doesn't work. ubuntu-mono 0.0.36 shows just black for the desktop background part of the user-desktop icon (as seen in Nautilus or in the Alt-Tab switcher). Reverting to 0.0.34 fixes this.
