Please describe the problem:
nautilus (both 2.10 and 2.11.x) with the newer gtk+ (2.7.x) and glib (2.7.x)
libraries causes strange graphical artifacts on the desktop when i use a jpeg or
png image.  basically the screen replicates itself in bizarre ways, either
dragging up, or tiling itself.



Steps to reproduce:
1. upgrade to glib-2.7.x and gtk+-2.7.x
2. change desktop background to image
3. watch the desktop do odd things


Actual results:
i'll try and attach some screenshots

Expected results:


Does this happen every time?
i've found strange interactions when choosing different styles, such as tiled,
scaled and full-screen.  for some reason, i've managed to get things stable with
the "Aqua Foot" background in tiled mode.  but many others don't give me any
working state.  it appears that png files cause more problems than jpg, but i
can't be certain--except for the fact that the only background images i got any
sense of stability out of were all jpegs.

Other information:
using xorg-x11-6.8.2 with radeon 7500.  also have cairo and glitz enabled.
