    Bug 797481 - crash on close of unsaved tabs by pressing [X]
    
    Pretty much the only place gnucash_sheet_get_block could crash is in
    g_table_index, either because the GTable's GArray has been deleted or
    the index is out of range. Add g_return_val_if_false tests for each
    possibility.
