Comment 15 for bug 363805

Add these lines at the end of /etc/apt/sources.list (you need a text editor with root privileges, I think you can do it from Synaptic and Adept too):

deb http://ppa.launchpad.net/sunab/ppa/ubuntu jaunty main
deb-src http://ppa.launchpad.net/sunab/ppa/ubuntu jaunty main

From the command line, run

sudo apt-get update

and then

sudo apt-get upgrade

Or use Synaptic or Adept to update your package list and to look for upgrade.

A new (unsigned) mlt++ version will be proposed for installation.

After that, run the configuration wizard from the Kdenlive configuration menu and this should work.
