[Yum] yum groupupdate ... RuntimeError: maximum recursion depth exceeded

[Nikola Ciprich]

Hi, seems like I may have found bug in python:
if I run you groupupdate group, on some of my servers it dies with 
following error:

I've tried with 3.2.12 too and problem persists. Strange thing is that 
it's happening on some machines and on some others not. I'm using centos 
5, so python is 2.4.3.
I'd appreciate any help with hunting this bug..
thanks a lot in advance..
