YUM error TypeError - puzzled

[neuromancer]

Hi all, I'm a noob at this YUM thing. I've installed everything and set the config. When I try an update, I get this message and I've searched high and low but can't seem to find any relevant info:

[root@vh1 root]# yum update

I'm using RHEL 3 AS in a Virtuozzo VZ, PSA 7.5.3
Purpose of getting YUM going is so I can install ClamAV and the like
Your help is appreciated, thx

wow, unable to find pid, thats a new one. My first thought is that this is something related to a custome environment on your vserver. Can you paste your yum.conf? Maybe its something subtle in there.
