Let's see if I can shed some light on this...

Look at issue 0003337 in the mantis bug tracker. This bug report has
very similar symptoms to what is described here.
That bug has been squashed only in the last month. That means that
there is no released version of kdenlive that will fix this issue.

If you have not done so already, fetch the latest git of mlt and
kdenlive, build and install those, and see if your issue pesists.

This also sounds like an old bug that has been fixed in the latest
git, and unrelated to the rendering from floxies bug.

This is interesting. I would like to know more about how you do this,
as I have also lost considerable amount of time when a save file got
corrupted.

Fetch the latest git of kdenlive and mlt, and install those. Then load
your project. You might have to delete the thumbnails to get kdenlive
to re-render them.
Also, if you disable proxies for the project, and save as a different
project, you might have some success that way.... however, proxy
handling has been greatly improved in the last month or so in
kdenlive.
