I get the same,
Format: NTSC Xvid 1500k 2 pass, aspect 16:9

The crash occurs with "2 pass" at 50% rendering (i.e. when the first pass is complete). It does not occur with "1 pass".
I get an ".avi" output file which contains video and audio, and also a ".avi_2pass_log file".

Ubuntu Oneiric.
kdenlive is version 0.8.1+svn20111029
melt is version 0.7.5+git20111021

Same here when rendering to DVD PAL 16:9 2 pass. It crashes in melt. Resulting .vob file has video but no audio.

Doing the same in 1 pass doesn't crash. Strangely it is also missing audio.

Rendering audio only has audio.

Ubuntu Studio 11.10
Version 0.8
Using KDE Development Platform 4.7.2 (4.7.2)

MLT melt 0.7.4

Ubuntu Oneiric amd64, everything up-to-date.

Kdenlive 0.8
Using KDE Development Platform 4.7.3 (4.7.3)
MLT melt 0.7.4

Can anyone tell me how to get a crash log like the original poster? I've tried the "Generate script" option and runnig it from the command line, but I don't get any more information than when running in the UI.

For me, I only get the crash with 2 pass. But even with 1 pass, the video comes out with no audio.

I switched this PPA from the kdenlive project:


And now everything works fine!
