plug fails to detect current user on fedora

[decathorpe]

The current user is displayed as (null), and nothing else seems to work right either (adding new accounts doesn't work, etc.).

These are the log messages I get from switchboard when opening the User Accounts plug:

I solved this problem:
public static unowned Act.User? get_current_user () {
if (current_user != null)
return current_user;
foreach (unowned Act.User temp_user in get_usermanager ().list_users ()) {
if (temp_user.get_user_name() == GLib.Environment.get_user_name ()) {
current_user = temp_user;
break;
}
}
return current_user;
}
P.S. adding new user not tested
