I'll hazard a guess that there is sqlite db is corrupt/duplicate primary 
key, but perhaps only with rpmforge. Try disabling that repo and check 
results.
yum --disablerepo=rpmforge update

If still no go, perhaps a
yum clean dbcache
and retrying will get it. if not
yum clean metadata
and try again.

Any output would be useful.
