Comment 2 kdeheld 2014-06-17 13:54:26 UTC 
Hello,
i dont understand why this is a duplicate.
I'm not using plasma-netbook, as stated in the other bug?
Or do i misunderstand the description?

Best wishes

Comment 3 Ivan Čukić 2014-06-17 16:06:55 UTC 
Both are the issues in KRunner library which Lancelot and Search and Launch use. The same bug, but exposed in two different places.
Comment 4 kdeheld 2014-06-18 07:05:56 UTC 
Hello,

thank you for this explanation.
