A bit of further information on this:

startkde (at least on ubuntu) has the following code:

# Set the path for Qt plugins provided by KDE
if test -n "$QT_PLUGIN_PATH"; then
   QT_PLUGIN_PATH="$QT_PLUGIN_PATH:`kde4-config --path qtplugins`"
else
   QT_PLUGIN_PATH="`kde4-config --path qtplugins`"
fi
export QT_PLUGIN_PATH


which then fires off makekdewidgets, etc, both on file open, and on 
configuration.
makekdewidgets takes ages because for some reason it tries to startup 
phonon of all things and fails, unknowingly, as my phonon setup's 
working fine.

Is this worth further investigation?
