You guys awake yet? The suspected KParts bug (Konqueror and KMail crashing on 
exit) is still open right?

Well it's 'caused' by the "delete (QWidget *)m_widget;" statement in 
kparts/part.cpp

Part::~Part()
{
  if ( m_widget )
  {
    // We need to disconnect first, to avoid calling it !
    disconnect( m_widget, SIGNAL( destroyed() ),
                this, SLOT( slotWidgetDestroyed() ) );
    kdDebug(1000) << "deleting widget " << m_widget->name() << endl;
        delete (QWidget *)m_widget; // <<<< sanders - I'm guilty!! <<<<<<
  }

  delete d;
}

Even without this delete statement m_widget is still deleted. But with it 
m_widget is attempted to be deleted twice. (Without the delete statement both 
KMail and Konqueror exit normally that is they don't segfault)

So this is very similar to the recent KStatusBar problem. I have reported 
that problem to Troll Tech so hopefully it will fix this KParts (or really 
QT) bug too.

BFN,
Don.
