Comment 2 for bug 1090490

New information about this issue. This only happens when you switch from plasma-netbook to plasma-desktop.
Steps to reproduce the bug:
1) Do a fresh install of Kubuntu in a netbook which loads plasma-netbook interface by default.
2) Switch to plasma-desktop interface via System Settings -> Workspace Behaviour -> Workpace -> Workspace Type.
3) After plasma-desktop is loaded, open Kickoff menu.
4) You will see a not functional Kopete launcher in favorites.

(Note that also you will have only one virtual desktop where having two virtual desktops is the expected default for Kubuntu plasma-desktop, and also minimize button is not there in Kwin ).
