I am not sure what is used to create the tracebacks. But I could
imagine that it uses stuff from sage.misc.sageinspect or
sage.misc.edit_module.

If this is the case, then it could help to use the patches from #9976
(merged in sage-4.7.1.alpha0) and #11298. Both patches greatly improve
the functionality of introspection (e.g., you can inspect
interactively defined Cython code). I will test whether they help with
your tracebacks.

And #11298 needs review, btw.

Cheers,
Simon
