Description of problem:
I was playing with spacewalk-sync-setup and observed a traceback.


Version-Release number of selected component (if applicable):
spacewalk-utils-2.0.2-8.el6sat.noarch


How reproducible:
always


Steps to Reproduce:
1. # spacewalk-sync-setup --ct --ss=<fqdn> --sl=<user> --sp=<pass>


Actual results:
Traceback (most recent call last):
  File "/usr/bin/spacewalk-sync-setup", line 610, in <module>
    master_cnx = connectTo(master_info)
  File "/usr/bin/spacewalk-sync-setup", line 299, in connectTo
    logging.info("Connecting to " + info['login'] + "@" + info['fqdn'])
TypeError: cannot concatenate 'str' and 'NoneType' objects

I believe this attempts to say me I have not provided master login info (server/user/pass), so maybe this is related or might be treated as similar issue falling into "insufficient input options verification" description:

# spacewalk-sync-setup --ct
Traceback (most recent call last):
  File "/usr/bin/spacewalk-sync-setup", line 605, in <module>
    config = setupConfig(options)
  File "/usr/bin/spacewalk-sync-setup", line 207, in setupConfig
    initializeConfig(opt, handle)
  File "/usr/bin/spacewalk-sync-setup", line 142, in initializeConfig
    hdr = hdr.replace('SLAVE', opt.slave)
TypeError: expected a character buffer object


Expected results:
There should be no traceback.


Additional info:
Probably would be nice to have some input sanitation before Sat560 GA.
