I am attempting to render a project, and while it works fine for the most part, at the end it states that "Rendering crashed", giving me this error:

I suspect that this is because of audio effects that I have applied. I've noticed that the video is available even if it states that it crashed, but I can't hear the sound there. The tracks that I can't hear correspond to the ones I have the audio effects (Gain or Volume (keyframable)) applied to.

You can find the full backtrace here:

If I try this with Sox Gain, I can hear the tracks fine (and with the right volume level, I believe), but it still says that it crashed. The only other audio effect I have on is Declipper, but I can hear the affected track fine as well, so it's quite puzzling. Any idea what is going wrong here?

Using openSUSE 11.4, Kdenlive 0.7.8.

I've just updated to Kdenlive 0.8 and tested a few more cases. I've managed to reproduce this and it's definitely because of Declipper. I don't get the crash message if I use Gain alone.

I don't do anything special with the sound, just cutting and editing different video+sound clips and always at the end I get this message. Also using openSUSE 11.4.
I get the same error message, simply by giving the command 'melt --version' which shows 'MLT melt 0.7.6'. The package is from the Packman repository and is 0.7.6-2.2.
