When I browse the list of users and order it by country, nothing happens. (neither asc nor desc ordering)
How to reproduce the bug:
- Browse list of users by navigating through: Site administration -> Users -> Accounts -> Browse list of users
- Order the list of users by country (more than once)
I suppose, the bug is related to the similar bug (http://tracker.moodle.org/browse/MDL-875), where an error with ordering users by country names (not codes) has been fixed, but another bug has been created.
