"Blank CD-ROM disc" icon when there is no disc in the drive

[Greg Bair]

i all,

Using 10.04 beta2.  When gnome starts, an icon shows up on the desktop 
for a blank CD-ROM.  When double-clicked, this goes to the burn:// 
folder in nautilus.  However, there is no disc in either drive, and when 
you attempt to actually burn files in this manner, the only option you 
receive is to make an ISO.

Any ideas on why this would show up if there's no disc in the drive?
