Issue 1) fixed upstream in https://github.com/OpenSCAP/openscap-daemon/commit/3adfa9fae427667b4d760bebeb75e54edd922346

Fixed In Version: openscap-daemon-0.1.9-1

Issue 2 is fixed but Issue 1 is still ocuring in openscap-daemon-0.1.9-1.el7.noarch (there should be no tracebacks):

We have agreed that the part 1 of the issue is actually fixed. There is a human-readable message and the displayed traceback enables user to find help more easily.
The part 2 has been widely agree as fixed, so I am moving the issue status to POST.
