--- Comment #9 from Andrea Iacovitti <aiacovitti@libero.it> ---
from khtml/rendering/render_media.cpp :
...
bool RenderMedia::eventFilter(QObject* o, QEvent* e)
{
    if (widget()->layout()->count() != 1 && mediaElement()->isVideo()) {
        switch(e->type()) {
        case QEvent::Enter:
    case QEvent::FocusIn:
        widget()->layout()->itemAt(1)->widget()->show();
        break;
    case QEvent::Leave:
    case QEvent::FocusOut:
        widget()->layout()->itemAt(1)->widget()->hide();
        break;
    default: ;
        }
    }

    return RenderWidget::eventFilter(o, e);
}
...

it crash when widget()->layout()->count() == 0,
because of an out of bound index access: widget()->layout()->itemAt(1)->show()
