Kdenlive 0.8.2 error dialod

Hi guys
I have a problem.
When I import a file, in a message dialog ask me "The process for the file protocol died unexpectedly."

Why?

Forums:

My version linux as "Ubuntu 10.04 lucid lynks"

Kdenlive 0.8.2 has a known problem with the KDE version that comes with Ubuntu 10.04. Please try the development version that is available from this repository:

https://launchpad.net/~sunab/+archive/kdenlive-svn

I'm solved the problem with this code:

sudo add-apt-repository ppa:kubuntu-ppa/backports
sudo apt-get update
sudo apt-get install kdebase

Install last version of KDE after that reboot.

Thank you for the answer.
