Multiple Icons Created for Removable media

["Colin Partridge" <colin perdicalis co uk>]

I've seen the following problem on a couple of machines, both of which are  
configured with dual displays, so I'm guessing that has something to do  
with it.

When mounting removable media such as a cdrom, floppy or usbdrive I get  
two icons created on the desktop.  Unmounting the media only removes one  
of the icons.

I can get rid of the icons by deleting them from ~/.gnome-desktop folder,  
but I'd appreciate some help on stopping this from happening in the first  
place.

Thanks
