startkde script has some qt4 relics

[Treeve Jelbert]

startkde has the following code:

# in case we have been started with full pathname spec without being in PATH
bindir=`echo "$0" | sed -n 's,^\(/.*\)/[^/][^/]*$,\1,p'`
if [ -n "$bindir" ]; then
  qbindir=`qtpaths --binaries-dir`
  qdbus=$qbindir/qdbus
  case $PATH in
    $bindir|$bindir:*|*:$bindir|*:$bindir:*) ;;
    *) PATH=$bindir:$PATH; export PATH;;
  esac
else
  qdbus=qdbus
fi


There are two problems with this

1.  qdbus is a relic of qt4

2. qtpaths fails if qtbase is not installed to a system default path.

How do I set the appropriate path before starting Plasma5 from sddm using 
/usr/share/xsessions/plasma.desktop?
 

In my case qt4 and qt5 are in different prefixes.
