Ok the new kdenlive just came out and it rocks,but it killed my openshot.Openshot will not start but kdenlive will,all this started after the kdenlive update,so if you have openshot and kdenlive installed with a "ppa" you will need to remove openshot and kdenlive,then disable the kdenlive "ppa",after that reinstall openshot and run it,after all that in-able the kdenlive ppa and reinstall it,,and run that too just to see if its ok. I did have a funny thing happen with my gnome panel after all this,the panel was there but no icons or clock,but this only happed on my laptop,i just had to logout and back a few time and it came back,if the problem sill there,reinstall the gnome panel and reboot.
