OK, just as a hack, I changed the code in SQLTABLE from:
r = field.represent(r)
To:
r = field.represent(r or [])
This eliminates the crash in the database administrator due to the
list:reference field. I hesitate to suggest this as a fix for the
issue because my understanding of this code is very superficial and
this may lead to unintended side effects. There may be good reason to
pass 'None' to field.represent() under other circumstances.
