[CentOS] update 5.4 problem using yum

Hi,

I have tried to update one of my servers to 5.4. I read the release notes
and ran yum clean all followed by yum update glibc\* without any problem,
I then ran yum update glibc\* which failed.

*** glibc detected *** /usr/bin/python: free(): invalid pointer:
0x0a98d660 ***
*** glibc detected *** /usr/bin/python: double free or corruption (out):
0x092e04c8 ***

Now I cannot run yum or rpm to restore the updated glibc packages. Any
idea's ? Did I miss something ?
