Subject: pitivi: CVE-2015-0855: Insecure use of os.system()


Luke Faraone reported the following issue in pitivi[0] to the Debian
security team on 13th of september, which got CVE-2015-0855 assigned.
There seems to have been a problem in propagating the CVE assigned
though, so we apologies for that. The assigned CVE is not mentioned in
the NEWS, but see below for the fixing commit.
