RT-TDDFT water absorption example does not run

Just Got Here
I'm trying to test RT-TDDFT functionality, starting with the example of water absorption at https://github.com/nwchemgit/nwchem/wiki/RT-TDDFT
( https://github.com/nwchemgit/nwchem/wiki/RT_TDDFT_h2o_abs.nw )

The example fails to run on 2 different systems.

On a Cray supercomputer with NWChem 6.8,
the run gets to "Closed-shell RT-TDDFT" and "Dipole and quadrupole matrices", and breaks there,
[13] Received an Error in Communication: (-1) 13:ga_norm_infinity_:nga_access_ptr:locate top failed:

On a Debian installation with NWChem 7.0.0,
it gets to "Closed-shell RT-TDDFT" and fails with
------------------------------------------------------------------------
rt_tddft_init_rtdb: failed to read print_dipcontribs from rtdb 0
------------------------------------------------------------------------
------------------------------------------------------------------------
current input line :
54: task dft rt_tddft
------------------------------------------------------------------------
....
[0] ARMCI Error: 0:rt_tddft_init_rtdb: failed to read print_dipcontribs from rtdb:


What am I (or my system configuration) doing wrong?
