I don't want to go too deeply into the issue, but I deleted some of the Nautilus-related .desktops in /usr/share/applications. What all should I have in the folder? I have:
nautilus-autorun-software.desktop
nautilus.desktop~
nautilus-folder-handler (copy).desktop
nautilus-folder-handler (copy).desktop~
nautilus-folder-handler.desktop~
nautilus-home.desktop~
My reason for asking is that my biggest problem occurs when using the dash search. If I search for "Documents", "Videos", etc. folders, they are unclickable. I think I may have broken something related to these files. Any help?
Edit: I used my LiveUSB, copied the Nautilus-related files to my install, and now it works. However, I have another problem with my dash search:

I have 2 "Downloads"... both work, but having two kind of bugs me. Any ideas?
