I have not used any PPA for Unity, and I got the same problem after upgrading to 13.10. I did not have unity-lens-friends installed and I just get a completely blank content are in the dash. I tried removing (and reinstalling) all unity-lens-* packages but so far, no luck.

After removing unity-lens-friends, there are now no lenses, and pressing Super brings up the Dash with a spinner next to the text box that never stops, and a blank content area.
