 I don't understand why this failed on Python 2.6.9 but succeeded (https
 ://travis-ci.org/travis-tahoe/tahoe-lafs/jobs/34190811) on the Python
 2.7.8 run of the same build. Also, a previous build with identical source
 (https://travis-ci.org/travis-tahoe/tahoe-lafs/jobs/34187776) passed on
 Python 2.6.9.

 (Travis isn't enabled yet for the main repo, but this is an identical test
 repo.)
