Description of problem:
gdm is being restarted when clicking users from the selector without asking a
password. I've seen interesting logs from gdm:

3.
  
Actual results:

Additional info:
This issue has been gone after installing iso-codes package here. so obviously
gdm is missing Requires: iso-codes.
