I added some debug lines to libsmb/trusts_util.c (see below), and the 
problem comes in the call:

if (!secrets_store_machine_password(new_trust_passwd, domain, 
sec_channel_type)) {...

then I think that tdb is not initialized and tdb-> points nothing:

   start a tdb transaction. No token is returned, as only a single
   transaction is allowed to be pending per tdb_context
int tdb_transaction_start(struct tdb_context *tdb)
         /* some sanity checks */
         if (tdb->read_only || (tdb->flags & TDB_INTERNAL) || 
tdb->traverse_read) {...
