today I installed spotify on ubuntu 12.04. The program seems to work quite well for now, so I tried to install spotify-lens. The installation went ok, but the lens doesn't appear in the dash. I tried to use the tool "lenstoggle" (which is my lens manager by now), but spotify-lens didn't appear on the list. So I rebboted the whole system, but it had no effect.
Any idea on how to fix it?
