### Description If mqueue is configured to use db_text, kamailio will not start.

#### Reproduction

Here's a simple config that will expose the issue: ``` loadmodule "xlog.so" loadmodule "db_text.so" loadmodule "mqueue.so" modparam("mqueue", "db_url", "text:///usr/local/etc/kamailio/dbtext") modparam("mqueue", "mqueue", "name=mqueue_dbtext;dbmode=1") # ------------------------- request routing logic -------------------

# main routing logic

route{ xlog("\n"); }

``` Content of the dbtext file: ``` $ cat /usr/local/etc/kamailio/dbtext/mqueue_dbtext id(int,auto) key(string) val(string) ```
