Hello, since recently, on one of my Plasma 5 installations using the search in the app-launcher (it's kickoff, isn't it?) looks something like this:

full desktop: https://dl.dropboxusercontent.com/u/121 ... ntries.png
[Imaqge description: Searched for "te", got only empty entries]

Clicking on them results only in a message about unknown URL.

Does anyone know the reason for that and how to get rid of this?
Thanks!
