Please describe the problem:
Having enabled the gst repositories for FC5, the package libtheora 1.0alpha7-1.gst.5 in reposirory gstreamer-0.10-deps.repo fails to update because it is not signed. All other packages update fine.

1. Enable repositories for FC5
    * gstreamer-0.10-deps.repo
    * gstreamer-0.10-gst.repo
    * gstreamer-0.10-apps.repo and import keys
2. Install GStreamer using "yum install gstreamer-universe" (in the past)
3. Run "yum update" today
