Hi Ken,
yes, that is a problem of old ffmpeg in cinelerra-cv. Einar works on
upgrading avlibs in Cinelerra-CV.
This means all encoding/decoding will be replaced with new libraries.
Testing and reporting encoding/decoding errors at the current state of
Cinelerra-CV is unimportant.
If you can/want to help, please compile  Cinelerra-*CVE*
The changes from there will be ported to Cinelerra-CV (CVO).

git clone git://git.cinelerra-cv.org/einar/cinelerra.git cv_einar
git pull
./configure --prefix=/opt/cin-cve --with-buildinfo=git/recompile
sudo make install

As a workaround, try to do

ffmpeg -i bad.mp4 -vcodec copy -acodec copy bad_new.mov

I tried that with your file. It works for me (in cinelerra-cv)
