I'm trying to set up a couple of desktop icons using iDesk but it's borked, got a screenshot of how they're coming out. I'm using the 0.5.x branch because I get seg faults with the 0.6 ones

Copy-pasted the config file off the site, I'm using xorg 6.8.1 w/ nvidia drivers and composite extension any help would be much appreciated.
