Accordingly, I have updated the packages "brasero" and "libbrasero-media0" from the repository "proposed" yesterday, and observed that with this update the problem is gone. And today, it seems to have found its way into the regular "jaunty-updates".

So, long story short, we can consider that the brasero-nautilus conflict has been solved and this bug report can be closed. Thanks again.
