The version in the repository is 0.10.0.5-6 The other components of gnonlin are 0.10.4-0.gst.2.5
Not sure how this got into the release notes component in the first place, but reassignment did not move it to the package owner. Manual reassignment now and removal of relnotes stuff.
In FC-5, the current version of gnonlin is 0.10.3, which is the last release that requires gstreamer < 0.10.3 (which is the version in FC5). Closing as WONTFIX.
