[Spacewalk-list] TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'

[Bruce McAlister]

Hi All,

I have been trying to dig in to why 2 of my CentOS 5 32-bit systems are 
failing configuration checks with the traceback shown at the end of the 
email.

The systems are on the spacewalk nightly builds for CentOS 5 32-bit.

When I schedule a configuration check, the job failes with:

Client execution returned "Fatal error in Python code occurred [[6]]" 
(code -1)

When I check the up2date log on the client, I see the following traceback:

[Wed Jun 17 08:33:59 2015] up2date
Traceback (most recent call last):
   File "/usr/sbin/rhn_check", line 356, in __run_action
     (status, message, data) = CheckCli.__do_call(method, params, kwargs)
   File "/usr/sbin/rhn_check", line 349, in __do_call
     retval = method(*params, **kwargs)
   File "/usr/share/rhn/actions/configfiles.py", line 342, in diff
     diff = fp.diff(file)
   File "/usr/share/rhn/config_common/file_utils.py", line 128, in diff
     temp_file, temp_dirs = self.process(file_struct)
   File "/usr/share/rhn/config_common/file_utils.py", line 48, in process
     fullpath = directory + file_struct['path']
exceptions.TypeError: unsupported operand type(s) for +: 'NoneType' and 
'str'

I am running the following package versions on both these servers (which 
appear to be up to date with the nightly channel):

# rpm -qa | egrep -i 'rhn|spacewalk|osad'
rhncfg-actions-5.10.81-1.el5
rhnlib-2.5.74-1.el5
rhn-client-tools-2.3.8-1.el5
rhnsd-5.0.15-1.el5
rhncfg-5.10.81-1.el5
rhn-setup-2.3.8-1.el5
rhncfg-client-5.10.81-1.el5
rhn-check-2.3.8-1.el5
yum-rhn-plugin-2.3.1-1.el5
osad-5.11.54-1.el5

I have several of these servers which I would like to update to the 
'latest' spacewalk clients, and these two were the first to be upgraded. 
I am now getting this particular issue, and I cannot seem to find where 
the issue lies.

Any pointers/tips/tricks/suggestions would be greatly appreciated.

Thanks
Bruce
