Hello moniac: I just booted into my number 2 hard drive on this machine where I have a PCLOS 2010 Gnome version installed. I installed OpenShot there and this is what it wanted to upgrade along with installing OpenShot and OpenShot docs, to be upgraded: freiOr-plugins, mlt, mlt-python, and python-pygoocanvas. After agreeing to all this , OpenShot was installed and the help files work on my Gnome install. I will try later on the KDE install and see if these programs are installed and upgraded, and will post back.
