rhn_register problem

[Thiago Vinhas de Moraes]

I'm trying to register to the RHN, and got the following error:

[root at techbyte root]# rhn_register --nox
Traceback (most recent call last):
  File "/usr/sbin/rhn_register", line 1183, in ?
    sys.exit(main() or 0)
  File "/usr/sbin/rhn_register", line 705, in main
    tui.main()
