I can confirm that setting UID_MIN 500 in /etc/login.defs completely fixes this problem.

The user ID is 501. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/834137 Title: user menu says [Invalid UTF-8] To manage notifications about this bug go to: https://bugs.launchpad.net/indicator-session/+bug/834137/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
