dial rules (on trunk) not saved

I am using Ubuntu 6.06.1 server with freepbx (using mysql-5.0.22, php-5.1.2 and apache2)+asterisk+misdn, compiled everything from svn today.

When I enter some dial rules on a trunk (tried with SIP and Custom trunks) and then click Submit, my dial rules are no logner showing in the dial rules box. Also they are not working after applying configuration, so I suppose they are not saved at all. I had this working before, when I was not using freepby with mysql. Everything else seems to work fine, and saves to DB normally.

Rules are I try to enter are like this one:
0038551+N.
