kdenlive just uses inigo to do the rendering. Even if the executable
is named kdenlive_renderer, it is just a copy of the inigo code with
some different console messaging to report progress. I believe the
problem is due to the bugs in the profiles system in the release 0.2.4
version of MLT. kdenlive launches inigo with "... -consumer
profile=blah" instead of the "MLT_PROFILE=blah inigo..." syntax I had
you use. Some bugs involved order of initialization of MLT various
components. There was a situation where the avformat producer would
initialize to the default (25fps from dv_pal) before it had knowledge
of the profile set on the consumer.

I believe you can reproduce the jerky kdenlive output from the command
line using:
$ inigo your.mov -consumer avformat:file.name real_time=0
profile=dv_ntsc {paste}
