f9 yum option --skip-broken: conflicting option string !

Hi, what do you make of this:

# yum -d 10 list
Loading "refresh-packagekit" plugin
Loading "skip-broken" plugin
Loaded plugins: refresh-packagekit, skip-broken
Running "config" handler for "skip-broken" plugin
Traceback (most recent call last):
   File "/usr/bin/yum", line 29, in <module>
     yummain.user_main(sys.argv[1:], exit_code=True)
   File "/usr/share/yum-cli/yummain.py", line 241, in user_main
     errcode = main(args)
   File "/usr/share/yum-cli/yummain.py", line 96, in main
     base.getOptionsConfig(args)
   File "/usr/share/yum-cli/cli.py", line 182, in getOptionsConfig
     disabled_plugins=self.optparser._splitArg(opts.disableplugins))

     startupconf.pluginconfpath,disabled_plugins)
   File "/usr/lib/python2.5/site-packages/yum/__init__.py", line 340, in

     self._check_conflict(option)
   File "/usr/lib/python2.5/optparse.py", line 989, in _check_conflict
     option)
optparse.OptionConflictError: option --skip-broken: conflicting option 
string(s): --skip-broken

In any case that is the result, no matter what normal parameters I 
supply, or even if I leave blank that would normally show the --help 
gives the same error.

Can't have blown my fresh f9 install {original /home directory} already 
could I ?

Happy to create a bug if it's not my fumbling ?
