The ASSERT has exposed a situation where collapsed borders are being calculated for a cell that is not in a table with collapsed borders! The problem seems to be with:

void RenderTable::recalcCollapsedBorders()
{
    if (m_collapsedBordersValid)
        return;
    m_collapsedBordersValid = true;
    m_collapsedBorders.clear();
    RenderObject* stop = nextInPreOrderAfterChildren();
    for (RenderObject* o = firstChild(); o && o != stop; o = o->nextInPreOrder()) {
        if (o->isTableCell())
            toRenderTableCell(o)->collectBorderValues(m_collapsedBorders);
    }
    RenderTableCell::sortBorderValues(m_collapsedBorders);
}

It is collecting border values for cells that are not in the RenderTable - I suspect a nested table.
