I suspected that this happens because we use KHTMLPart
begin()/write()/end(). Probably I hit the bullseye because this kind of
simple application reproduces the problem. (testiView is the main widget
for a simple application made with a KDevelop wizard.)

testiView::testiView(QWidget *)
{
	//opens the html file named "html.html" from the cwd.
	QFile file("html.html");
	file.open(QIODevice::ReadOnly);
	QTextStream in(&file);
	m_text = in.readAll();
	file.close();

	// adds a line editor and khtmlview.
	// line editor let's the user give the anchor
	// without restarting.
	m_part = new KHTMLPart(this);
	QVBoxLayout* lo = new QVBoxLayout(this);
	m_lineEdit = new QLineEdit(this);
	lo->addWidget(m_lineEdit);
	lo->addWidget(m_part->view());
	QObject::connect(m_lineEdit, SIGNAL(returnPressed()), this,
SLOT(go()));
	go();
}
void testiView::go()
{
	m_part->begin();
	m_part->write(m_text);
	m_part->end();
	m_part->gotoAnchor(QString(m_lineEdit->text()));
}

This will work and show the bug with any html file which has anchors.

I will soon report this with bugs.kde.org and add the complete test
application so that you don't have to write it manually.
