Ah Ok before I try that I should say there is a kde4 folder in '/usr/share'.
However there is only one folder in the kde4 folder, 'Services'. When I open that there is 'ServiceMenus', an 'apt.protocol' file and an 'apt+http.protocol' file. When I open 'ServiceMenus' there is a 'cabextract.desktop' folder and if I click on 'cabextract.desktop' then I get a message saying 'there was an error launching the application'.
I thought that could be relevant.
There is also an okular folder in '/usr/share'.
