When I use USB storage device such as a 30GB black iPod video, 2 GB PNY
memory stick, or Sony PSP-1000 are connected, they mount well.
However, upon right-clicking on the disk and hitting "Eject device", it
does not remove the icon from the XFCE desktop or Thunar. Instead, it
remains, now either able to be unmounted (which removes the icon, but
not in Thunar if removed from the desktop or vice-versa) or remounted.
If the USB device is removed prior to removing the device, the icon
cannot be removed unless the USB device is reinserted, instead saying
that /dev/sdf/ cannot be found.

I'd report this to my distro (Xubuntu 8.10) but I'm hearing on a forum topic http://linuxoutlaws.com/forums/viewtopic.php?f=9&t=968&p=16322#p16322 that a person on Slackware has the same problem, so I'm also reporting here. Sorry, I'm new to the whole bug report deal so I'm not entirely sure where this goes.
