Comment 8 for bug 85608

I just had a similar problem also.
Running Feisty with the latest updates.

The trash was showing files in /dev in my trash can...

I believe it had a line "/dev -" in my .trash_entry_cache (sorry, I just rm -rf'd the file). Renaming the .trash_entry_cache file and doing a "sudo /etc/init.d/gdm restart" fixed the issue.

I'm not sure of the cause of this, but I'm 95% sure it happened after a boot with fsck.
