REVISION SUMMARY
  I had every toplevel entry doubled in kontact's configuration dialog
  due to $XDG_DATA_DIRS=<myPrefix>/share:/usr/share
  which led to parsing both
  <myPrefix>/share/kontact/ksettingsdialog/knotes.setdlg
  and
  /usr/share/kontact/ksettingsdialog/knotes.setdlg
  
  Solution: do this in two steps (collect names, then look up each name to
  only the most local variant of it). This was more natural with
  KStandardDirs API, I admit.
