Location info not save during user register

When i created new user or user register location info is present on register form but not save after submit.
If i edit user and add location info - it is saved.
i have 2 installations of my site with same configuration, but diffirent db - MySQL and MariaDB.
Problem exist only on MariaDB.
Anyone can test location_user in MariaDB?
or may be any ideas?
Thanks, and sorry for my english.
