Yum _sqlitecache.so error

I upgraded Fedora from 6 to 8 and yum is not working.  I have tried
installing the yum and python packages again but this has not helped.

$ yum
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

   /usr/lib/python2.5/site-packages/_sqlitecache.so: undefined symbol:
g_string_chunk_insert_len

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.5.1 (r251:54863, Oct 30 2007, 13:54:11)
[GCC 4.1.2 20070925 (Red Hat 4.1.2-33)]

Here are the installed packages.

$ rpm -qa rpm\* yum\* python sqlite |sort
python-2.5.1-15.fc8
rpm-4.4.2.2-3.fc8
rpm-build-4.4.2.2-3.fc8
rpm-devel-4.4.2.2-3.fc8
rpm-libs-4.4.2.2-3.fc8
rpm-python-4.4.2.2-3.fc8
sqlite-3.4.2-3.fc8
yum-3.2.7-1.fc8
yum-metadata-parser-1.1.2-1.fc8
yum-updatesd-0.7-1.fc8
yum-utils-1.1.8-1.fc8


Any help would be greatly appreciated.


Thanks
