HI KKDE maintainers.
Lword & other koffice applications core dump on startup and it occurs in
kfilewidget.cpp.  I am talking about  building koffice and klibs out of the
svn repository

The change that fixes is to apply checks for null pointers in
KFileWidget::showEvent().  I don't know what these pointers are, and perhaps
it is an error in koffice applications, but a simple check as shown below
does catch the error and allow kword to come up.



void KFileWidget::showEvent(QShowEvent* event)
{

  if (d) {  // this is a new check
    if ( !d->hasView ) { // delayed view-creation
      if (d->ops) { // this is a new check
        d->ops->setView( KFile::Default );
        d->ops->view()->setSizePolicy( QSizePolicy( QSizePolicy::Maximum,
QSizePolicy::Maximum ) );
      }
        d->hasView = true;
    }
    if (d->ops) // this is a new check
      d->ops->clearHistory();
  }
  QWidget::showEvent(event);
