asterisk users - Aug 2014 - DPMA: User SIP settings missing or invalid

Asterisk 12.5.0
DPMA 12.0_2.0.0
Ubuntu 12.04 64 bit

[2014-08-21 16:37:49] WARNING[5797]: phone_users.c:5236 set_and_process: 
User SIP settings missing or invalid

I'm getting the error message above when DPMA is enabled, using a fresh 
build but with my config files from Asterisk 11.  Any idea what it 
means?  I can't find the "phone_users.c" file to examine the
source
(assuming it is part of DPMA which has no source, rather than Asterisk).

I can't tell that anything is not working - I can configure and connect 
at least one Digium phone.
