As far as I can see, there is no information there that helps me locate the problem, beyond knowing it is one of the files associated with my course.

The first commit you should get integrated ASAP.
The second commit is my attempt to get the error message to include some useful information about what is going on. Sadly, it is a failed attempt. I can't work out how to get the kind of information you need to make the error diagnosable, but this is the kind of information that the backup system should include when it throws an exception.
Sorry for the rant above. It was written in a moment of stress.
However, there was one useful commit there, which I have not submitted for integration.
Please can we have this on 2.1 and master branches.
I thought I had submitted this for integration, but somehow I must have clicked the wrong button.
crap, I remember perfectly I had to play with those params because there was something "extra" in moodle_exception. It seems the extra gone and I didn't realized it. Also, I've here that exception highly hacked dumping everything to logs file. Sure that has not helped detecting the problem.
Thanks!
Integrated!
tested by throwing manually one backup_step_exception and checking everything arrives / is displayed as expected.
Ciao 
If there is a will, there is a way, and you found it! Thanks!
Hang on a sec, and I will push a branch to github with some ideas.
