Again, sorry to disappoint you guys with this Ubuntu upgrade. Hopefully, they get it fixed right away. So, my advice is to stick with the previous versions of what you have rather upgrade. I guess, we all learned a lesson.
Thank you for your patience.
(Update) I have another solution for your video editing needs on this post: http://ooboontoo.blogspot.com/2011/10/kdenlive-problem-easy-fix-stupeflix.html
It looks promising.
