put_file fails but no exception is raised

[stilwelb]

It appears there are situations where a transfer can fail in put_file, but no exception is raised. It would be nice if when this scenario happens , an exception is raised like f9dce5f, so this particular request can be retried. An excerpt of the error is below:
