Now that I am doing some serious editing with Kdenlive 0.8, I'm seeing
something similar, but not sure if it's related.

I have an ogg in the audio timeline, I can shorten it, but fade out
does not work correctly. It reverts back to 100% volume for the last
second. I have tried keyframable volume as well, with a similar
effect: 100% volume on the last second, even when extending the audio
clip and putting the audio level to 0% for that time. Cutting off the
last second just moves the 100% volume bit to the last second of the
shorter clip.

I am now doing a test render to see if it shows up in the rendered
video. I am using video from a Canon 550D, so it's a bit big to send

Kind regards,
