Description of problem:
I run command  "rhncfg-client diff" when files wasn't deployed on system and application failed.

Version-Release number of selected component (if applicable):
rhncfg-client-5.10.27-8.el6sat.noarch

How reproducible:
always

Steps to Reproduce:
1. Create and subscribe system to configuration channel
2. Add new file to this configuration channel
3. Before the file was deployed, run command rhncfg-client diff
4. rhncfg-client failed with error "UnboundLocalError: local variable 'statinfo' referenced before assignment"
  
Actual results:
>> rhncfg-client diff
  File "/usr/bin/rhncfg-client", line 38, in <module>
    sys.exit(Main().main() or 0)
  File "/usr/share/rhn/config_common/rhn_main.py", line 195, in main
    handler.run()
  File "/usr/share/rhn/config_client/handler_base.py", line 66, in run
    self._process_file(src, dst, file, ftype, file_info)
  File "/usr/share/rhn/config_client/rhncfgcli_diff.py", line 53, in _process_file
    (self.options.display_diff or get_config('display_diff')))))
  File "/usr/share/rhn/config_common/file_utils.py", line 161, in diff
    (dst_content, dst_name, dst_time, dst_stat) = f_content(dst, dstname)
  File "/usr/share/rhn/config_common/file_utils.py", line 158, in f_content
    return (content, name, f_time, statinfo)
UnboundLocalError: local variable 'statinfo' referenced before assignment


Expected results:
Without error and get correct diff of files.

Additional info:
Package rhncfg-client-5.9.27-17.el6.noarch.rpm worked correctly.
