I just tried k3b-0.9-0.fdr.7.1. I have used many versions of k3b before (build myself) and never had a problem, until now. k3bsetup doesn't work. When run normally from menu (asks for root pw...), it hangs. A process usermod -G ... seems to be stuck. When I do su, then run k3bsetup, it completes, but fails to set permissions for /usr/bin/cdrecord and devices.
