[Users] lookup problem

Hello, here is the situation : one openSER statefull and one openSER registrar on different ports; both db_mode are DB_ONLY. when a UAC A rings UAC B, everything's fine until openSER statefull receives ACK message : as a matter of fact, the domain name was changed before receiving ACK message, therefore, openSER needs to do /lookup("location"); /Unfortunately, openSER could not find the UAC A in database. i had a look to the mysql query made while ACK is treated and actually the username part of address_of_record disappeared : /select ... from location where username=''; /It seems that when /print_where/ (modules/mysql/dbase.c) writes "where" part in mysql query, this function calls /val2str/ (modules/mysql/val.c) which will translate the value to a string. Until this call, everything's just fine, but when /val2str /calls _/mysql_real_escape_string/_, this last function returns an empty string. Any clue? Has anyone already face this problem?
