I received the same error from pitivi Also on ubuntu 9.10 amd64. For me, error only occurs when video is added from sources into the project and I try to play it back. The error only began to occur after I ran kdenlive at the same time. Before then, I did not have any problems with pitivi.
I was editing mpeg encoded videos.
