Comment 2 for bug 707239

This is a bit confusing. You say you're using Ubuntu 11.04, yet your bug report indicates that it is Ubuntu 10.10, and that the installation media was Ubuntu 9.10...

I'll assume this is ubuntu 10.10 and you're not actually running a dev version of ubuntu.

Could you try without fading out at the end?
Also check if there are errors when running pitivi from a terminal.

If you're able to test pitivi git too, that would be interesting.
