The problem appears to be a list with a value in regular_include_lists
that is maybe a bare listname. the values in regular_include_lists and
regular_exclude_lists are list posting addresses, e.g.
otherlist at example.com, not plain list names.

This is the problem. It looks empty in the web gui, but it contains a
null line. Select the entire text box and clear it.
