Yum update yum ERROR ?!

[Luciano Costa <ltcnikit@xxxxxxxxx>]

 Hi fedora's users,

I tried to do a yum update and when it is processing shows the message below:


--> Processing Dependency: libnewt.so.0.51 for package: kudzu

    (rescode, restring) = self.resolveDeps()

    (checkdep, missing, conflict, errormsgs) = self._processConflict(dep)
  File "/usr/lib/python2.3/site-packages/yum/depsolve.py", line 492, in _processConflict
    uplist = self.up.getUpdatesList(name=confname)
UnboundLocalError: local variable 'confname' referenced before assignment

 What is happening ?!? What should I do, please ?! 

Thanks !!

Luciano
