I don't really use it anymore (replaced it with Zotero) and don't have time to maintain it, but it is still being developed upstream (as of late 2011): http://sourceforge.net/projects/bibus-biblio/ There is a 1.5.2 release available, see also: https://bugzilla.redhat.com/show_bug.cgi?id=757675 Hopefully it will go to a better home.
