Subject: [PATCH 4/9] Pass on the error message when rel_path is invalid
"Module path must be a string" is not a useful error message when the
reason the module path isn't a string is because the string it was got
replaced with an invalid with an error message for some other reason.
Also fixes a few memory leaks on early exits.
