Hi,
when ::-webkit-scrollbar css are apply on body and scrollbar are visible, when
you change html, webcore crash on ScrollBar destruction.
I find a temporary solution :
1- hide webkit scrollbar
2- reinit html to empty
3- reactive webkit scrollbar
4- load new html
5- call repaint().



m_MailBody->page()->mainFrame()->setScrollBarPolicy (
Qt::Horizontal,Qt::ScrollBarAlwaysOff);
m_MailBody->page()->mainFrame()->setScrollBarPolicy (
Qt::Vertical,Qt::ScrollBarAlwaysOff);
m_MailBody->setHtml("");
m_MailBody->page()->mainFrame()->setScrollBarPolicy (
Qt::Horizontal,Qt::ScrollBarAsNeeded);
m_MailBody->page()->mainFrame()->setScrollBarPolicy (
Qt::Vertical,Qt::ScrollBarAsNeeded);  
m_MailBody->setHtml(html);
m_MailBody->repaint();
