Desktop keeps showing files that are no longer there

Hours after downloading a few pdf files with Chrome into the Desktop and being done with them, I went to delete them.
I was surprised to find a file called something.pdf.chdownload. These are the temporary files that Chrome creates while downloading the files, then it renames them to their final filename without the .chrdownload suffix when they are complete. All of the files had been downloaded completely and succesfully (I had actually opened all of them) so this file shouldn't exist.

And indeed, when I went to download it, I got an error "Cannot move <filename> to trash. Delete it permanently?" (this is actually stupid in the first place: the reason why I'm getting this error, it turns out, is that the file does not exist, so it makes no sense to give me the option to permanently delete it, which will fail for the exact same reason).
So I chose "delete", and got an error again, that the file could not be deleted. I retried several times and finally looked at "details" and found out that the source of the error was "no such file or directory".

So, the file was not there.

So why the fuck was it being shown on the desktop if it was no longer there? I can assume it might happen some rare times (it's a bug anyway) that you for some reason "miss" when a file ceases existing, and hence it is still falsely visible on the desktop. But there should come a point where Nautilus "realises" the file no longer exists and stops showing it. In other words, the contents of the desktop should be "refreshed" from time to time or on certain events. And trying to delete a file, triggering an error that says that the file doesn't fucking exist, should be such a case where you refresh the information and stop showing a file that doesn't exist.

It's pathetic that you keep showing it forever until I kill and restart nautilus or fucking reboot.

I'm sick of reporting such idiotic bugs on Nautilus. Ubuntu, for fuck's sake, switch to some better, decently maintained file manager. Nautilus is CRAP.
