My idea was along the lines of 
bool KURLRequester::eventFilter( QObject *obj, QEvent *ev )
{
    if ( obj == d->edit || obj == d->combo ) {
        if ( ev->type() == QEvent::FocusIn || ev->type() == QEvent::FocusOut ) {
            // Forward focusin/focusout events to the urlrequester; needed by file form element in khtml
            qApp->sendEvent( this, ev );
        }
    }
    return QWidget::eventFilter( obj, ev );
}
with widget->installEventFilter( this ) only, not installEventFilter(this).

Does this work?

BTW I just had a look at qcombobox (which uses a lineedit as its focusproxy),
and this is almost exactly what it does: event filter on the lineedit, and 
        } else if ( event->type() == QEvent::FocusIn ) {
            focusInEvent( (QFocusEvent *)event );
        } else if ( event->type() == QEvent::FocusOut ) {
            focusOutEvent( (QFocusEvent *)event );
But I'm guessing that just calling focusInEvent/focusOutEvent isn't enough in our
case, we need event filters on the container widget (the urlrequester in our case)
to be triggered.
