Without some sense of what happened, this is hard to debug. But it looks 
as if the crash is in here:
     Tabular::idx_type Tabular::numberOfCellsInRow(row_type const row) const
{
     idx_type result = 0;
     for (col_type c = 0; c < ncols(); ++c)
         if (cell_info[row][c].multicolumn != 
Tabular::CELL_PART_OF_MULTICOLUMN)
             ++result;
     return result;
}

which makes me suspect that maybe a column got deleted without 
everything having been updated properly.
