make_summary issue at end of LINC_calibrator

I am getting a crash at the end of LINC-calibrator in make_summary (after the cal_solutions file has been created) and have an updated pull of LINC from the end of September. The full log is on http://www.jb.man.ac.uk/~njj/slurm-92481.out but the bit around the crash site is
