Comment 1 Andrej Nemec 2017-01-10 14:55:30 UTC

Created ark tracking bugs for this issue:

Affects: fedora-all [bug 1411822]

Comment 2 Than Ngo 2017-01-10 15:26:22 UTC

it's already fixed in fedora git branch

Comment 3 Doran Moppert 2017-01-20 04:23:34 UTC

Unable to reproduce on ark-4 in Red Hat Enterprise Linux 7:  the script is opened in an internal viewer rather than executed.

According to a comment on the Debian tracker, the affected functionality was introduced post ark-15.11.80.
