I have this problem too. Ubuntu Edgy. Don't know if it is relevant, but if I start k3b from a terminal I get this message when I try to update the permissions in the setup:
qstring_to_xtp result code -2 Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed -- k3bsetup fails to change permissions of programs https://launchpad.net/bugs/54264 -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
