I'm having the same problem.  The only fix that works is re-updating the
yum RPM (using --force):
  rpm -Uvh --force  /var/cache/yum/freshrpms-fc2/packages/yum-2.0.7-3.1.fc.fr.noarch.rpm

The badness is not from the python code being changed.  It's likely a
corrupt data file, but not /etc/yum.conf.

I seemed to have caused it again by pressing control-c while starting yum
(or it could just be that I interrupted yum before it could error).

The error occurs without any network traffice taking place (I traced it
with ethereal).

Below are three invocations of yum, the first interrupted by the control-c
that might be the problem.  Notice the third invocation uses a invalid yum
argument.
