hi..

so, we all know we use dptrs in libraries to maintain binary compatibility. 
but i'm seeing them used more and more in plugins such as plasmoids. this is 
really, really annoying when trying to debug things because then we end up 
with backtraces like this:

Application: Plasma Widget Viewer (plasmoidviewer), signal: Segmentation fault
[KCrash Handler]
#6  0x00000011 in ?? ()
#7  0xa98ab67b in Kickoff::RecentlyUsedModel::setNameDisplayOrder 
(this=0x82f2b58, displayOrder=Kickoff::NameBeforeDescription)
    at 
/home/aseigo/kde4/KDE/kdebase/workspace/plasma/applets/kickoff/core/recentlyusedmodel.cpp:213
#8  0xa98f9b1b in Kickoff::Launcher::setShowAppsByName (this=0x82b1fc8, 
showAppsByName=true) at 

not good. there's no reason for dptrs except for in libraries that are keeping 
binary compat. please don't use dptrs otherwise, if only for the sake of 
debugging. thanks.
