[Spacewalk-list] Cannot register oracle linux cannot marshal None unless allow_none is enabled

[Net Warrior]

Hi guys, good morning.

I'm having issues trying to register an oracle linux client, I was able to
register one before and that's the only one I have registered at this
moment, now it seems that something got updated in the repo or something
else , and I get this error:

An error has occurred:
<type 'exceptions.TypeError'>
See /var/log/up2date for more information

File "/usr/lib64/python2.6/xmlrpclib.py", line 699, in __dump
    f(self, value, write)
  File "/usr/lib64/python2.6/xmlrpclib.py", line 780, in dump_struct
    dump(v, write)
  File "/usr/lib64/python2.6/xmlrpclib.py", line 699, in __dump

    raise TypeError, "cannot marshal None unless allow_none is enabled"
<type 'exceptions.TypeError'>: cannot marshal None unless allow_none is
