[SR-Users] dmq/dmq_userloc crash on startup (kamailio 4.3.0)

Hello,
at the quick look it seems that dmq_usrloc was not updated with the
latest format of the serialized structure returned by usrloc when
fetching the contacts. It seems to use the same function as nathelper
(which use it for sending keepalives) and that is returning both contact
and received addresses, but dmq_usrloc seem to take only one of them
(like in the older versions of the function).
I am traveling for a while, but I guess some other devs that use dmq can
look at it.
Cheers,
Daniel
