Hi,
At the request of the Google Font Directory (http://code.google.com/webfonts) Yanone Kaffeesatz licence changed to OFL (was CC-BY). The new version has been pushed in Fedora: http://koji.fedoraproject.org/koji/buildinfo?buildID=186370
This should be fine as the OFL is Fedora's preferred font licence (with the GPL, provided the standard font exception is not missing) http://fedoraproject.org/wiki/Legal_considerations_for_fonts#Preferred_Licen...
Regards,
