Use str(e) instead of e.args[0].
Calling str() on an instance of BaseException will give something at least as good as `e.args[0].
Actually, even self.Error.manifold_error(e) but I'd prefer being explicit.

test_singular_matrices or something like that?

Would a simpler, more obviously singular matrix, like all zeros, work here as well?

Yes, matrix with all zeros would work here as well. But I just wanted to point out that regular matrix can crash the code as well.
