Comment 13 for bug 839319

@kroq-gar78:
Can you provide any more information? Has it ever worked for you? Are you still using 11.10? Is your Clementine database in /home/<username>/.config/Clementine/clementine.db?

Also, open a terminal and try the following:
 killall -9 clementine-scope
 python /usr/lib/unity-music-lens/clementine-scope

This should kill and restart the scope process and output stuff to the terminal. You should get the following:
  Search changed to: ''
  Updated tracks from Clementine database
Followed by "Search changed to: <search>" when you search with the lens. Let me know if it has anything else instead.
