error on yum update

[Joel Rees]

Doing a yum update just now. After

Package Openoffice.org-langpack-ja_JP.ppc 1:3.1.0-11.3.fc11 set to be  
updated

it spits out

/usr/lib/python2.6/site-packages/yum/packages.py:387: UnicodeWarning:  
Unicode unequal comparison failed to convert both arguments to  
Unicode - interpreting them as being unequal
   if reqn != n:

and then continues with

Package openoffice.org-math.ppc 1:3.1.0-11.3.fc11 set to be updated

Does this need to be reported somewhere or just ignored?
