  Seeing the line mentioned and the code underneath it may due to some error in your kactitivity database where an entry has an empty name or path.
  
  You can remove your activity database with 
  rm ~/.local/share/kactivitymanagerd/resources/database
  And restart dolphin
  
  Or try to find the error with like :
  sqlitebrowser ~/.local/share/kactivitymanagerd/resources/database
