I just upgraded my kamailio (1.5) to the latest version, but after restarting kamailio the calling of allow_trusted() is failing with the following error: "ERROR:permissions:allow_trusted: no connection to database". Permissions module is using 'db_mode 1'

I noticed there has been a change in the permissions/trusted.c code so i'm wondering if this is the cause of this problem ?

version: kamailio 1.5.2-notls (i386/linux)
flags: STATISTICS, USE_IPV6, USE_TCP, DISABLE_NAGLE, USE_MCAST, SHM_MMAP, PKG_MALLOC, F_MALLOC, FAST_LOCK-ADAPTIVE_WAIT
ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, PKG_SIZE 4194304
poll method support: poll, epoll_lt, epoll_et, sigio_rt, select.
