Code review comment for lp:~alexei-kornienko/testrepository/bug-1271133

The data is already available in in the file attachment 'import errors' from subunit - the reason for the inscrutable error from testr is that I hadn't finished gluing the layers together fully.

Whats needed, if you want to work on it - and please do! - is to take 'out', run it through subunit's parser to separate structured data from unstructured, and show all packets that are not test enumerations.

That will show the error strings from testtools cleanly, immediately.
