The only solution is to downgrade to version 2.20.x of GDM or wait for GNOME 3 where it maybe is fixed. The downgrade is not recommended.

There is a solution to this problem.
Make sure that the user you want to hide is not logged on and use, in terminal of course, the command usermod.
sudo usermod -u 999 (or any other available number) NAME (of the account you want to hide).

So, why does this work then?
Each account is given a unique UID (user identification) and it starts with 1000 and goes up. The login screen only shows the sccounts that have a number of 1000 or higher.
Groups and special accounts are numbered below 1000 so they don't show in the login screen.

Hope this wasn't to complicated
