Yum update yum ERROR ?!

 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
--> Processing Conflict: kernel conflicts isdn4k-utils< 3.2-32
--> Processing Dependency: xorg-x11-filesystem>= 0.99.2-3 for package: libXext-devel

    (result, resultmsgs) = base.buildTransaction()
  File "/usr/lib/python2.3/site-packages/yum/__init__.py", line 174, in buildTransaction
    (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 !!
