When I attempt a search after hitting Super, the spinner spins, but no results come up once the spinning stops. I'm not sure what changed that caused this. I had a newer kernel installed, but I have since reverted back to the default kernel.

I also followed this guide: http://www.webupd8.org/2011/04/how-to-reset-unity-launcher-icons-or.html

• Alt+F2 does not work.
• The packages unity-place-applications and unity-place-files are installed.

But search still doesn't function correctly.
