This bug is part of the non-responsive maintainer procedure for rdieter, following https://docs.fedoraproject.org/en-US/fesco/Policy_for_nonresponsive_package_maintainers/. Please respond if you are still active in Fedora and want to maintain libunity.
Rex is generally still very much involved in Fedora. We're looking into this particular package.
https://bugzilla.redhat.com/show_bug.cgi?id=1951440 is now MODIFIED. I'd say we can close this one.
