babune junitxml not well formed on Python 2.7

[Martin Packman]

All babune runs on Python 2.7 have failed at the end with an xml parser error trying to read the results, which in essence is:

    org.xml.sax.SAXParseException: XML document structures must start and end within the same entity

The problem document is generated with subunit2junitxml from subunit which uses pyjunitxml to write the xml.

The issue may be from a particular test failure output that Python 2.7 happens to trigger rather than an incompatibility in the generation code. Either way, pyjunitxml should be ensuring it's creating well formed output.

So, this isn't 2.7 specific but instead is caused by the unicode handling in pyjunitxml, as can also be seen on the babune windows bot now that the thread leaks have been squashed down a bit:

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 4099: ordinal not in range(128)

Results are now working on babune so I'll mark this as fix released in bzr as well.
