baseurl: what is this code supposed to do?

Hello,

I just stumbled across this piece of code in khtml_part.cpp at line 1683 in 
KHTMLPart::begin()

  KURL baseurl;

  if ( !m_url.isEmpty() )
  {
    KURL title( baseurl );
    title.setRef( QString::null );
    title.setQuery( QString::null );
    emit setWindowCaption( title.prettyURL() );
  }

baseurl is defined, thus being initialized to an empty url. Then, without ever 
assigning anything to baseurl, it is assigned to title in the if clause.

Lateron, baseurl is set as the document's base url, but hasn't been assigned 
to inbetween either.

In KDE 3.0.4, baseurl is initialized in the if clause as follows:

    KURL::List lst = KURL::split( m_url );
    if ( !lst.isEmpty() )
      baseurl = *lst.begin();

Was the initialization removed intentionally? And where is it actually set 
(and if it isn't, why does KHTML still work)?
