[CentOS] Depsolving errors whilst upgrading Centos 5.6 -> 5.7

I have a dedicated server from 1&1 (http://1and1.co.uk/). A 'yum list
updates' today showed me that the 5.7 update was available (it's
probably been there for a while, I don't check that often).

But running 'yum update' gives the following error:

Running rpm_check_debug

I haven't reported the bug yet. I thought I'd see if anyone here had
seen anything similar first.

Cheers,

Dave...
