Debug logs for unit tests appear to contain some corrupted characters

[Henry Nash]

When running our unit tests as part of jenkins the "output" file are merged into one output file using subunit. The resulting files appear to contain corrupted characters, e.g.:

From a jenkins test:

Is this some kind of artefact of not handling the subunit output correctly?

[Steve Martinelli (stevemar)]

The ``output`` file is no longer generated, and from what I can tell this is no longer an issue.
