i missed reading post #5 where you gave a list of repos
this was in it
epel.repo rpmfusion-free.repo
epel-testing.repo rpmfusion-free-updates.repo
unfortunately this tells us nothing about there state
Are they on or off ?
run this and post back
this outputs a list of ONLY the ones turned on
you also have "fedora-rawhide.repo rpmfusion-free-updates-testing.repo" in your list
if that is on ( it is fedora 12 ) and you have installed ANY of them your system might be beyond repair
and a full reinstall would be needed .
